+# Instantiator
+
+This library provides a way of avoiding usage of constructors when instantiating PHP classes.

+[![Latest Unstable Version](https://poser.pugx.org/doctrine/instantiator/v/unstable.png)](https://packagist.org/packages/doctrine/instantiator)
+
+## Installation
+
+The suggested installation method is via [composer](https://getcomposer.org/):
+
+```sh
+php composer.phar require "doctrine/instantiator:~1.0.3"
+```
+
+## Usage
+
+The instantiator is able to create new instances of any class without using the constructor or any API of the class
+itself:
+
+```php
+$instantiator = new \Doctrine\Instantiator\Instantiator();
+
+$instance = $instantiator->instantiate('My\\ClassName\\Here');
+```
+
+## Contributing
+
+Please read the [CONTRIBUTING.md](CONTRIBUTING.md) contents if you wish to help out!
+
+## Credits
+
+This library was migrated from [ocramius/instantiator](https://github.com/Ocramius/Instantiator), which
+has been donated to the doctrine organization, and which is now deprecated in favour of this package.

+
+* Ensuring Content-Length is not stripped from a request when it is `0`.
+* Added more information to stream wrapper exceptions.
+* Message parser will no longer throw warnings for malformed messages.
+* Giving a valid cache TTL when max-age is 0.
+
+## 3.9.2 - 2014-09-10
+
+* Retrying "Connection died, retrying a fresh connect" curl errors.

+
+## 3.9.1 - 2014-05-07
+
+* Added a fix to ReadLimitEntityBody to ensure it doesn't infinitely loop.
+* Added a fix to the stream checksum function so that when the first read
+  returns a falsey value, it still continues to consume the stream until EOF.
+
+## 3.9.0 - 2014-04-23
+
+* `null`, `false`, and `"_guzzle_blank_"` all now serialize as an empty value
+  with no trailing "=". See dc1d824277.
+* No longer performing an MD5 check on the cacert each time the phar is used,
+  but rather copying the cacert to the temp directory.
+* `"0"` can now be added as a URL path
+* Deleting cookies that are set to empty
+* If-Modified-Since is no longer unnecessarily added to the CachePlugin
+* Cookie path matching now follows RFC 6265 s5.1.4
+* Updated service descriptions are now added to a service client's composite
+  factory.
+* MockPlugin now throws an exception if the queue is empty.
+* Properly parsing URLs that start with "http" but are not absolute

+
+## 3.7.0 - 2013-06-10
+
+* See UPGRADING.md for more information on how to upgrade.
+* Requests now support the ability to specify an array of $options when creating a request to more easily modify a
+  request. You can pass a 'request.options' configuration setting to a client to apply default request options to
+  every request created by a client (e.g. default query string variables, headers, curl options, etc).
+* Added a static facade class that allows you to use Guzzle with static methods and mount the class to `\Guzzle`.
+  See `Guzzle\Http\StaticClient::mount`.
+* Added `command.request_options` to `Guzzle\Service\Command\AbstractCommand` to pass request options to requests
+      created by a command (e.g. custom headers, query string variables, timeout settings, etc).
+* Stream size in `Guzzle\Stream\PhpStreamRequestFactory` will now be set if Content-Length is returned in the
+  headers of a response
+* Added `Guzzle\Common\Collection::setPath($path, $value)` to set a value into an array using a nested key
+  (e.g. `$collection->setPath('foo/baz/bar', 'test'); echo $collection['foo']['bar']['bar'];`)
+* ServiceBuilders now support storing and retrieving arbitrary data
+* CachePlugin can now purge all resources for a given URI
+* CachePlugin can automatically purge matching cached items when a non-idempotent request is sent to a resource
+* CachePlugin now uses the Vary header to determine if a resource is a cache hit
+* `Guzzle\Http\Message\Response` now implements `\Serializable`
+* Added `Guzzle\Cache\CacheAdapterFactory::fromCache()` to more easily create cache adapters
+* `Guzzle\Service\ClientInterface::execute()` now accepts an array, single command, or Traversable
+* Fixed a bug in `Guzzle\Http\Message\Header\Link::addLink()`
+* Better handling of calculating the size of a stream in `Guzzle\Stream\Stream` using fstat() and caching the size
+* `Guzzle\Common\Exception\ExceptionCollection` now creates a more readable exception message
+* Fixing BC break: Added back the MonologLogAdapter implementation rather than extending from PsrLog so that older
+  Symfony users can still use the old version of Monolog.
+* Fixing BC break: Added the implementation back in for `Guzzle\Http\Message\AbstractMessage::getTokenizedHeader()`.
+  Now triggering an E_USER_DEPRECATED warning when used. Use `$message->getHeader()->parseParams()`.
+* Several performance improvements to `Guzzle\Common\Collection`
+* Added an `$options` argument to the end of the following methods of `Guzzle\Http\ClientInterface`:
+  createRequest, head, delete, put, patch, post, options, prepareRequest
+* Added an `$options` argument to the end of `Guzzle\Http\Message\Request\RequestFactoryInterface::createRequest()`
+* Added an `applyOptions()` method to `Guzzle\Http\Message\Request\RequestFactoryInterface`
+* Changed `Guzzle\Http\ClientInterface::get($uri = null, $headers = null, $body = null)` to
+  `Guzzle\Http\ClientInterface::get($uri = null, $headers = null, $options = array())`. You can still pass in a
+  resource, string, or EntityBody into the $options parameter to specify the download location of the response.
+* Changed `Guzzle\Common\Collection::__construct($data)` to no longer accepts a null value for `$data` but a
+  default `array()`
+* Added `Guzzle\Stream\StreamInterface::isRepeatable`
+* Removed `Guzzle\Http\ClientInterface::setDefaultHeaders(). Use
+  $client->getConfig()->setPath('request.options/headers/{header_name}', 'value')`. or
+  $client->getConfig()->setPath('request.options/headers', array('header_name' => 'value'))`.
+* Removed `Guzzle\Http\ClientInterface::getDefaultHeaders(). Use $client->getConfig()->getPath('request.options/headers')`.
+* Removed `Guzzle\Http\ClientInterface::expandTemplate()`
+* Removed `Guzzle\Http\ClientInterface::setRequestFactory()`
+* Removed `Guzzle\Http\ClientInterface::getCurlMulti()`
+* Removed `Guzzle\Http\Message\RequestInterface::canCache`
+* Removed `Guzzle\Http\Message\RequestInterface::setIsRedirect`
+* Removed `Guzzle\Http\Message\RequestInterface::isRedirect`
+* Made `Guzzle\Http\Client::expandTemplate` and `getUriTemplate` protected methods.
+* You can now enable E_USER_DEPRECATED warnings to see if you are using a deprecated method by setting
+  `Guzzle\Common\Version::$emitWarnings` to true.
+* Marked `Guzzle\Http\Message\Request::isResponseBodyRepeatable()` as deprecated. Use
+      `$request->getResponseBody()->isRepeatable()` instead.
+* Marked `Guzzle\Http\Message\Request::canCache()` as deprecated. Use
+  `Guzzle\Plugin\Cache\DefaultCanCacheStrategy->canCacheRequest()` instead.
+* Marked `Guzzle\Http\Message\Request::canCache()` as deprecated. Use
+  `Guzzle\Plugin\Cache\DefaultCanCacheStrategy->canCacheRequest()` instead.
+* Marked `Guzzle\Http\Message\Request::setIsRedirect()` as deprecated. Use the HistoryPlugin instead.
+* Marked `Guzzle\Http\Message\Request::isRedirect()` as deprecated. Use the HistoryPlugin instead.
+* Marked `Guzzle\Cache\CacheAdapterFactory::factory()` as deprecated
+* Marked 'command.headers', 'command.response_body' and 'command.on_complete' as deprecated for AbstractCommand.
+  These will work through Guzzle 4.0
+* Marked 'request.params' for `Guzzle\Http\Client` as deprecated. Use [request.options][params].
+* Marked `Guzzle\Service\Client::enableMagicMethods()` as deprecated. Magic methods can no longer be disabled on a Guzzle\Service\Client.
+* Marked `Guzzle\Service\Client::getDefaultHeaders()` as deprecated. Use $client->getConfig()->getPath('request.options/headers')`.
+* Marked `Guzzle\Service\Client::setDefaultHeaders()` as deprecated. Use $client->getConfig()->setPath('request.options/headers/{header_name}', 'value')`.
+* Marked `Guzzle\Parser\Url\UrlParser` as deprecated. Just use PHP's `parse_url()` and percent encode your UTF-8.
+* Marked `Guzzle\Common\Collection::inject()` as deprecated.
+* Marked `Guzzle\Plugin\CurlAuth\CurlAuthPlugin` as deprecated. Use `$client->getConfig()->setPath('request.options/auth', array('user', 'pass', 'Basic|Digest');`
+* CacheKeyProviderInterface and DefaultCacheKeyProvider are no longer used. All of this logic is handled in a
+  CacheStorageInterface. These two objects and interface will be removed in a future version.
+* Always setting X-cache headers on cached responses
+* Default cache TTLs are now handled by the CacheStorageInterface of a CachePlugin
+* `CacheStorageInterface::cache($key, Response $response, $ttl = null)` has changed to `cache(RequestInterface
+  $request, Response $response);`
+* `CacheStorageInterface::fetch($key)` has changed to `fetch(RequestInterface $request);`
+* `CacheStorageInterface::delete($key)` has changed to `delete(RequestInterface $request);`
+* Added `CacheStorageInterface::purge($url)`
+* `DefaultRevalidation::__construct(CacheKeyProviderInterface $cacheKey, CacheStorageInterface $cache, CachePlugin
+  $plugin)` has changed to `DefaultRevalidation::__construct(CacheStorageInterface $cache,
+  CanCacheStrategyInterface $canCache = null)`
+* Added `RevalidationInterface::shouldRevalidate(RequestInterface $request, Response $response)`
+
+## 3.6.0 - 2013-05-29
+
+* ServiceDescription now implements ToArrayInterface
+* Added command.hidden_params to blacklist certain headers from being treated as additionalParameters
+* Guzzle can now correctly parse incomplete URLs
+* Mixed casing of headers are now forced to be a single consistent casing across all values for that header.
+* Messages internally use a HeaderCollection object to delegate handling case-insensitive header resolution
+* Removed the whole changedHeader() function system of messages because all header changes now go through addHeader().
+* Specific header implementations can be created for complex headers. When a message creates a header, it uses a
+  HeaderFactory which can map specific headers to specific header classes. There is now a Link header and
+  CacheControl header implementation.
+* Removed from interface: Guzzle\Http\ClientInterface::setUriTemplate
+* Removed from interface: Guzzle\Http\ClientInterface::setCurlMulti()
+* Removed Guzzle\Http\Message\Request::receivedRequestHeader() and implemented this functionality in
+  Guzzle\Http\Curl\RequestMediator
+* Removed the optional $asString parameter from MessageInterface::getHeader(). Just cast the header to a string.
+* Removed the optional $tryChunkedTransfer option from Guzzle\Http\Message\EntityEnclosingRequestInterface
+* Removed the $asObjects argument from Guzzle\Http\Message\MessageInterface::getHeaders()
+* Removed Guzzle\Parser\ParserRegister::get(). Use getParser()
+* Removed Guzzle\Parser\ParserRegister::set(). Use registerParser().
+* All response header helper functions return a string rather than mixing Header objects and strings inconsistently
+* Removed cURL blacklist support. This is no longer necessary now that Expect, Accept, etc are managed by Guzzle
+  directly via interfaces
+* Removed the injecting of a request object onto a response object. The methods to get and set a request still exist
+  but are a no-op until removed.
+* Most classes that used to require a ``Guzzle\Service\Command\CommandInterface` typehint now request a
+  `Guzzle\Service\Command\ArrayCommandInterface`.
+* Added `Guzzle\Http\Message\RequestInterface::startResponse()` to the RequestInterface to handle injecting a response
+  on a request while the request is still being transferred
+* The ability to case-insensitively search for header values
+* Guzzle\Http\Message\Header::hasExactHeader
+* Guzzle\Http\Message\Header::raw. Use getAll()
+* Deprecated cache control specific methods on Guzzle\Http\Message\AbstractMessage. Use the CacheControl header object
+  instead.
+* `Guzzle\Service\Command\CommandInterface` now extends from ToArrayInterface and ArrayAccess
+* Added the ability to cast Model objects to a string to view debug information.
+
+## 3.5.0 - 2013-05-13
+
+* Bug: Fixed a regression so that request responses are parsed only once per oncomplete event rather than multiple times
+* Bug: Better cleanup of one-time events accross the board (when an event is meant to fire once, it will now remove
+  itself from the EventDispatcher)
+* Bug: `Guzzle\Log\MessageFormatter` now properly writes "total_time" and "connect_time" values
+* Bug: Cloning an EntityEnclosingRequest now clones the EntityBody too
+* Bug: Fixed an undefined index error when parsing nested JSON responses with a sentAs parameter that reference a
+  non-existent key
+* Bug: All __call() method arguments are now required (helps with mocking frameworks)
+* Deprecating Response::getRequest() and now using a shallow clone of a request object to remove a circular reference
+  to help with refcount based garbage collection of resources created by sending a request
+* Deprecating ZF1 cache and log adapters. These will be removed in the next major version.
+* Deprecating `Response::getPreviousResponse()` (method signature still exists, but it'sdeprecated). Use the
+  HistoryPlugin for a history.
+* Added a `responseBody` alias for the `response_body` location
+* Refactored internals to no longer rely on Response::getRequest()
+* HistoryPlugin can now be cast to a string
+* HistoryPlugin now logs transactions rather than requests and responses to more accurately keep track of the requests
+  and responses that are sent over the wire
+* Added `getEffectiveUrl()` and `getRedirectCount()` to Response objects
+
+## 3.4.3 - 2013-04-30
+
+* Bug fix: Fixing bug introduced in 3.4.2 where redirect responses are duplicated on the final redirected response
+* Added a check to re-extract the temp cacert bundle from the phar before sending each request
+
+## 3.4.2 - 2013-04-29
+
+* Bug fix: Stream objects now work correctly with "a" and "a+" modes
+* Bug fix: Removing `Transfer-Encoding: chunked` header when a Content-Length is present
+* Bug fix: AsyncPlugin no longer forces HEAD requests
+* Bug fix: DateTime timezones are now properly handled when using the service description schema formatter
+* Bug fix: CachePlugin now properly handles stale-if-error directives when a request to the origin server fails
+* Setting a response on a request will write to the custom request body from the response body if one is specified
+* LogPlugin now writes to php://output when STDERR is undefined
+* Added the ability to set multiple POST files for the same key in a single call

+Guzzle Upgrade Guide
+====================
+
+3.6 to 3.7
+----------
+
+### Deprecations
+
+- You can now enable E_USER_DEPRECATED warnings to see if you are using any deprecated methods.:
+
+```php
+\Guzzle\Common\Version::$emitWarnings = true;
+```
+
+The following APIs and options have been marked as deprecated:
+
+- Marked `Guzzle\Http\Message\Request::isResponseBodyRepeatable()` as deprecated. Use `$request->getResponseBody()->isRepeatable()` instead.
+- Marked `Guzzle\Http\Message\Request::canCache()` as deprecated. Use `Guzzle\Plugin\Cache\DefaultCanCacheStrategy->canCacheRequest()` instead.
+- Marked `Guzzle\Http\Message\Request::canCache()` as deprecated. Use `Guzzle\Plugin\Cache\DefaultCanCacheStrategy->canCacheRequest()` instead.
+- Marked `Guzzle\Http\Message\Request::setIsRedirect()` as deprecated. Use the HistoryPlugin instead.
+- Marked `Guzzle\Http\Message\Request::isRedirect()` as deprecated. Use the HistoryPlugin instead.
+- Marked `Guzzle\Cache\CacheAdapterFactory::factory()` as deprecated
+- Marked `Guzzle\Service\Client::enableMagicMethods()` as deprecated. Magic methods can no longer be disabled on a Guzzle\Service\Client.
+- Marked `Guzzle\Parser\Url\UrlParser` as deprecated. Just use PHP's `parse_url()` and percent encode your UTF-8.
+- Marked `Guzzle\Common\Collection::inject()` as deprecated.
+- Marked `Guzzle\Plugin\CurlAuth\CurlAuthPlugin` as deprecated. Use
+  `$client->getConfig()->setPath('request.options/auth', array('user', 'pass', 'Basic|Digest|NTLM|Any'));` or
+  `$client->setDefaultOption('auth', array('user', 'pass', 'Basic|Digest|NTLM|Any'));`
+
+3.7 introduces `request.options` as a parameter for a client configuration and as an optional argument to all creational
+request methods. When paired with a client's configuration settings, these options allow you to specify default settings
+for various aspects of a request. Because these options make other previous configuration options redundant, several
+configuration options and methods of a client and AbstractCommand have been deprecated.
+
+- Marked `Guzzle\Service\Client::getDefaultHeaders()` as deprecated. Use `$client->getDefaultOption('headers')`.
+- Marked `Guzzle\Service\Client::setDefaultHeaders()` as deprecated. Use `$client->setDefaultOption('headers/{header_name}', 'value')`.
+- Marked 'request.params' for `Guzzle\Http\Client` as deprecated. Use `$client->setDefaultOption('params/{param_name}', 'value')`
+- Marked 'command.headers', 'command.response_body' and 'command.on_complete' as deprecated for AbstractCommand. These will work through Guzzle 4.0
+
+        $command = $client->getCommand('foo', array(
+            'command.headers' => array('Test' => '123'),
+            'command.response_body' => '/path/to/file'
+        ));
+
+        // Should be changed to:
+
+        $command = $client->getCommand('foo', array(
+            'command.request_options' => array(
+                'headers' => array('Test' => '123'),
+                'save_as' => '/path/to/file'
+            )
+        ));
+
+### Interface changes
+
+Additions and changes (you will need to update any implementations or subclasses you may have created):
+
+- Added an `$options` argument to the end of the following methods of `Guzzle\Http\ClientInterface`:
+  createRequest, head, delete, put, patch, post, options, prepareRequest
+- Added an `$options` argument to the end of `Guzzle\Http\Message\Request\RequestFactoryInterface::createRequest()`
+- Added an `applyOptions()` method to `Guzzle\Http\Message\Request\RequestFactoryInterface`
+- Changed `Guzzle\Http\ClientInterface::get($uri = null, $headers = null, $body = null)` to
+  `Guzzle\Http\ClientInterface::get($uri = null, $headers = null, $options = array())`. You can still pass in a
+  resource, string, or EntityBody into the $options parameter to specify the download location of the response.
+- Changed `Guzzle\Common\Collection::__construct($data)` to no longer accepts a null value for `$data` but a
+  default `array()`
+- Added `Guzzle\Stream\StreamInterface::isRepeatable`
+- Made `Guzzle\Http\Client::expandTemplate` and `getUriTemplate` protected methods.
+
+The following methods were removed from interfaces. All of these methods are still available in the concrete classes
+that implement them, but you should update your code to use alternative methods:
+
+- Removed `Guzzle\Http\ClientInterface::setDefaultHeaders(). Use
+  `$client->getConfig()->setPath('request.options/headers/{header_name}', 'value')`. or
+  `$client->getConfig()->setPath('request.options/headers', array('header_name' => 'value'))` or
+  `$client->setDefaultOption('headers/{header_name}', 'value')`. or
+  `$client->setDefaultOption('headers', array('header_name' => 'value'))`.
+- Removed `Guzzle\Http\ClientInterface::getDefaultHeaders(). Use `$client->getConfig()->getPath('request.options/headers')`.
+- Removed `Guzzle\Http\ClientInterface::expandTemplate()`. This is an implementation detail.
+- Removed `Guzzle\Http\ClientInterface::setRequestFactory()`. This is an implementation detail.
+- Removed `Guzzle\Http\ClientInterface::getCurlMulti()`. This is a very specific implementation detail.
+- Removed `Guzzle\Http\Message\RequestInterface::canCache`. Use the CachePlugin.
+- Removed `Guzzle\Http\Message\RequestInterface::setIsRedirect`. Use the HistoryPlugin.
+- Removed `Guzzle\Http\Message\RequestInterface::isRedirect`. Use the HistoryPlugin.
+
+### Cache plugin breaking changes
+
+- CacheKeyProviderInterface and DefaultCacheKeyProvider are no longer used. All of this logic is handled in a
+  CacheStorageInterface. These two objects and interface will be removed in a future version.
+- Always setting X-cache headers on cached responses
+- Default cache TTLs are now handled by the CacheStorageInterface of a CachePlugin
+- `CacheStorageInterface::cache($key, Response $response, $ttl = null)` has changed to `cache(RequestInterface
+  $request, Response $response);`
+- `CacheStorageInterface::fetch($key)` has changed to `fetch(RequestInterface $request);`
+- `CacheStorageInterface::delete($key)` has changed to `delete(RequestInterface $request);`
+- Added `CacheStorageInterface::purge($url)`
+- `DefaultRevalidation::__construct(CacheKeyProviderInterface $cacheKey, CacheStorageInterface $cache, CachePlugin
+  $plugin)` has changed to `DefaultRevalidation::__construct(CacheStorageInterface $cache,
+  CanCacheStrategyInterface $canCache = null)`
+- Added `RevalidationInterface::shouldRevalidate(RequestInterface $request, Response $response)`
+
+3.5 to 3.6
+----------
+
+* Mixed casing of headers are now forced to be a single consistent casing across all values for that header.
+* Messages internally use a HeaderCollection object to delegate handling case-insensitive header resolution
+* Removed the whole changedHeader() function system of messages because all header changes now go through addHeader().
+  For example, setHeader() first removes the header using unset on a HeaderCollection and then calls addHeader().
+  Keeping the Host header and URL host in sync is now handled by overriding the addHeader method in Request.
+* Specific header implementations can be created for complex headers. When a message creates a header, it uses a
+  HeaderFactory which can map specific headers to specific header classes. There is now a Link header and
+  CacheControl header implementation.
+* Moved getLinks() from Response to just be used on a Link header object.
+
+If you previously relied on Guzzle\Http\Message\Header::raw(), then you will need to update your code to use the
+HeaderInterface (e.g. toArray(), getAll(), etc).
+
+### Interface changes
+
+* Removed from interface: Guzzle\Http\ClientInterface::setUriTemplate
+* Removed from interface: Guzzle\Http\ClientInterface::setCurlMulti()
+* Removed Guzzle\Http\Message\Request::receivedRequestHeader() and implemented this functionality in
+  Guzzle\Http\Curl\RequestMediator
+* Removed the optional $asString parameter from MessageInterface::getHeader(). Just cast the header to a string.
+* Removed the optional $tryChunkedTransfer option from Guzzle\Http\Message\EntityEnclosingRequestInterface
+* Removed the $asObjects argument from Guzzle\Http\Message\MessageInterface::getHeaders()
+
+### Removed deprecated functions
+
+* Removed Guzzle\Parser\ParserRegister::get(). Use getParser()
+* Removed Guzzle\Parser\ParserRegister::set(). Use registerParser().
+
+### Deprecations
+
+* The ability to case-insensitively search for header values
+* Guzzle\Http\Message\Header::hasExactHeader
+* Guzzle\Http\Message\Header::raw. Use getAll()
+* Deprecated cache control specific methods on Guzzle\Http\Message\AbstractMessage. Use the CacheControl header object
+  instead.
+
+### Other changes
+
+* All response header helper functions return a string rather than mixing Header objects and strings inconsistently
+* Removed cURL blacklist support. This is no longer necessary now that Expect, Accept, etc are managed by Guzzle
+  directly via interfaces
+* Removed the injecting of a request object onto a response object. The methods to get and set a request still exist
+  but are a no-op until removed.
+* Most classes that used to require a ``Guzzle\Service\Command\CommandInterface` typehint now request a
+  `Guzzle\Service\Command\ArrayCommandInterface`.
+* Added `Guzzle\Http\Message\RequestInterface::startResponse()` to the RequestInterface to handle injecting a response
+  on a request while the request is still being transferred
+* `Guzzle\Service\Command\CommandInterface` now extends from ToArrayInterface and ArrayAccess
+
+3.3 to 3.4
+----------
+
+Base URLs of a client now follow the rules of http://tools.ietf.org/html/rfc3986#section-5.2.2 when merging URLs.
+
+3.2 to 3.3
+----------
+
+### Response::getEtag() quote stripping removed
+
+`Guzzle\Http\Message\Response::getEtag()` no longer strips quotes around the ETag response header
+
+### Removed `Guzzle\Http\Utils`
+
+The `Guzzle\Http\Utils` class was removed. This class was only used for testing.
+
+### Stream wrapper and type
+
+`Guzzle\Stream\Stream::getWrapper()` and `Guzzle\Stream\Stream::getSteamType()` are no longer converted to lowercase.
+
+### curl.emit_io became emit_io
+
+Emitting IO events from a RequestMediator is now a parameter that must be set in a request's curl options using the
+'emit_io' key. This was previously set under a request's parameters using 'curl.emit_io'
+
+3.1 to 3.2
+----------
+
+### CurlMulti is no longer reused globally
+
+Before 3.2, the same CurlMulti object was reused globally for each client. This can cause issue where plugins added
+to a single client can pollute requests dispatched from other clients.
+
+If you still wish to reuse the same CurlMulti object with each client, then you can add a listener to the
+ServiceBuilder's `service_builder.create_client` event to inject a custom CurlMulti object into each client as it is
+created.
+
+```php
+$multi = new Guzzle\Http\Curl\CurlMulti();
+$builder = Guzzle\Service\Builder\ServiceBuilder::factory('/path/to/config.json');
+$builder->addListener('service_builder.create_client', function ($event) use ($multi) {
+    $event['client']->setCurlMulti($multi);
+}
+});
+```
+
+### No default path
+
+URLs no longer have a default path value of '/' if no path was specified.
+
+Before:
+
+```php
+$request = $client->get('http://www.foo.com');
+echo $request->getUrl();
+// >> http://www.foo.com/
+```
+
+After:
+
+```php
+$request = $client->get('http://www.foo.com');
+echo $request->getUrl();
+// >> http://www.foo.com
+```
+
+### Less verbose BadResponseException
+
+The exception message for `Guzzle\Http\Exception\BadResponseException` no longer contains the full HTTP request and
+response information. You can, however, get access to the request and response object by calling `getRequest()` or
+`getResponse()` on the exception object.
+
+### Query parameter aggregation
+
+Multi-valued query parameters are no longer aggregated using a callback function. `Guzzle\Http\Query` now has a
+setAggregator() method that accepts a `Guzzle\Http\QueryAggregator\QueryAggregatorInterface` object. This object is
+responsible for handling the aggregation of multi-valued query string variables into a flattened hash.
+
+2.8 to 3.x
+----------
+
+### Guzzle\Service\Inspector
+
+Change `\Guzzle\Service\Inspector::fromConfig` to `\Guzzle\Common\Collection::fromConfig`
+
+**Before**
+
+```php
+use Guzzle\Service\Inspector;
+
+class YourClient extends \Guzzle\Service\Client
+{
+    public static function factory($config = array())
+    {
+        $default = array();
+        $required = array('base_url', 'username', 'api_key');
+        $config = Inspector::fromConfig($config, $default, $required);
+
+        $client = new self(
+            $config->get('base_url'),
+            $config->get('username'),
+            $config->get('api_key')
+        );
+        $client->setConfig($config);
+
+        $client->setDescription(ServiceDescription::factory(__DIR__ . DIRECTORY_SEPARATOR . 'client.json'));
+
+        return $client;
+    }
+```
+
+**After**
+
+```php
+use Guzzle\Common\Collection;
+
+class YourClient extends \Guzzle\Service\Client
+{
+    public static function factory($config = array())
+    {
+        $default = array();
+        $required = array('base_url', 'username', 'api_key');
+        $config = Collection::fromConfig($config, $default, $required);
+
+        $client = new self(
+            $config->get('base_url'),
+            $config->get('username'),
+            $config->get('api_key')
+        );
+        $client->setConfig($config);
+
+        $client->setDescription(ServiceDescription::factory(__DIR__ . DIRECTORY_SEPARATOR . 'client.json'));
+
+        return $client;
+    }
+```
+

+```
+

+
+### Guzzle\Common\Inflection\Inflector
+
+Namespace is now `Guzzle\Inflection\Inflector`
+
+### Guzzle\Http\Plugin
+
+Namespace is now `Guzzle\Plugin`. Many other changes occur within this namespace and are detailed in their own sections below.
+
+### Guzzle\Http\Plugin\LogPlugin and Guzzle\Common\Log
+
+Now `Guzzle\Plugin\Log\LogPlugin` and `Guzzle\Log` respectively.
+
+**Before**
+
+```php
+use Guzzle\Common\Log\ClosureLogAdapter;
+use Guzzle\Http\Plugin\LogPlugin;
+
+/** @var \Guzzle\Http\Client */
+$client;
+
+// $verbosity is an integer indicating desired message verbosity level
+$client->addSubscriber(new LogPlugin(new ClosureLogAdapter(function($m) { echo $m; }, $verbosity = LogPlugin::LOG_VERBOSE);
+```
+
+**After**
+
+```php
+use Guzzle\Log\ClosureLogAdapter;
+use Guzzle\Log\MessageFormatter;
+use Guzzle\Plugin\Log\LogPlugin;
+
+/** @var \Guzzle\Http\Client */
+$client;
+
+// $format is a string indicating desired message format -- @see MessageFormatter
+$client->addSubscriber(new LogPlugin(new ClosureLogAdapter(function($m) { echo $m; }, $format = MessageFormatter::DEBUG_FORMAT);
+```
+
+### Guzzle\Http\Plugin\CurlAuthPlugin
+
+Now `Guzzle\Plugin\CurlAuth\CurlAuthPlugin`.
+
+### Guzzle\Http\Plugin\ExponentialBackoffPlugin
+
+Now `Guzzle\Plugin\Backoff\BackoffPlugin`, and other changes.
+
+**Before**
+
+```php
+use Guzzle\Http\Plugin\ExponentialBackoffPlugin;
+
+$backoffPlugin = new ExponentialBackoffPlugin($maxRetries, array_merge(
+        ExponentialBackoffPlugin::getDefaultFailureCodes(), array(429)
+    ));
+
+$client->addSubscriber($backoffPlugin);
+```
+
+**After**
+
+```php
+use Guzzle\Plugin\Backoff\BackoffPlugin;
+use Guzzle\Plugin\Backoff\HttpBackoffStrategy;
+
+// Use convenient factory method instead -- see implementation for ideas of what
+// you can do with chaining backoff strategies
+$backoffPlugin = BackoffPlugin::getExponentialBackoff($maxRetries, array_merge(
+        HttpBackoffStrategy::getDefaultFailureCodes(), array(429)
+    ));
+$client->addSubscriber($backoffPlugin);
+```
+
+### Known Issues
+
+#### [BUG] Accept-Encoding header behavior changed unintentionally.
+
+(See #217) (Fixed in 09daeb8c666fb44499a0646d655a8ae36456575e)
+
+In version 2.8 setting the `Accept-Encoding` header would set the CURLOPT_ENCODING option, which permitted cURL to
+properly handle gzip/deflate compressed responses from the server. In versions affected by this bug this does not happen.
+See issue #217 for a workaround, or use a version containing the fix.

+========
+Batching
+========
+
+Guzzle provides a fairly generic and very customizable batching framework that allows developers to efficiently
+transfer requests in parallel.
+
+Sending requests and commands in parallel
+-----------------------------------------
+
+You can send HTTP requests in parallel by passing an array of ``Guzzle\Http\Message\RequestInterface`` objects to
+``Guzzle\Http\Client::send()``:
+
+.. code-block:: php
+
+    $responses = $client->send(array(
+        $client->get('http://www.example.com/foo'),
+        $client->get('http://www.example.com/baz')
+        $client->get('http://www.example.com/bar')
+    ));
+
+You can send commands in parallel by passing an array of ``Guzzle\Service\Command\CommandInterface`` objects
+``Guzzle\Service\Client::execute()``:
+
+.. code-block:: php
+
+    $commands = $client->execute(array(
+        $client->getCommand('foo'),
+        $client->getCommand('baz'),
+        $client->getCommand('bar')
+    ));
+
+These approaches work well for most use-cases.  When you need more control over the requests that are sent in
+parallel or you need to send a large number of requests, you need to use the functionality provided in the
+``Guzzle\Batch`` namespace.
+
+Batching overview
+-----------------
+
+The batch object, ``Guzzle\Batch\Batch``, is a queue.  You add requests to the queue until you are ready to transfer
+all of the requests.  In order to efficiently transfer the items in the queue, the batch object delegates the
+responsibility of dividing the queue into manageable parts to a divisor (``Guzzle\Batch\BatchDivisorInterface``).
+The batch object then iterates over each array of items created by the divisor and sends them to the batch object's
+``Guzzle\Batch\BatchTransferInterface``.
+
+.. code-block:: php
+
+    use Guzzle\Batch\Batch;
+    use Guzzle\Http\BatchRequestTransfer;
+
+    // BatchRequestTransfer acts as both the divisor and transfer strategy
+    $transferStrategy = new BatchRequestTransfer(10);
+    $divisorStrategy = $transferStrategy;
+
+    $batch = new Batch($transferStrategy, $divisorStrategy);
+
+    // Add some requests to the batch queue
+    $batch->add($request1)
+        ->add($request2)
+        ->add($request3);
+
+    // Flush the queue and retrieve the flushed items
+    $arrayOfTransferredRequests = $batch->flush();
+
+.. note::
+
+    You might find that your transfer strategy will need to act as both the divisor and transfer strategy.
+
+Using the BatchBuilder
+----------------------
+
+The ``Guzzle\Batch\BatchBuilder`` makes it easier to create batch objects.  The batch builder also provides an easier
+way to add additional behaviors to your batch object.
+
+Transferring requests
+~~~~~~~~~~~~~~~~~~~~~
+
+The ``Guzzle\Http\BatchRequestTransfer`` class efficiently transfers HTTP requests in parallel by grouping batches of
+requests by the curl_multi handle that is used to transfer the requests.
+
+.. code-block:: php
+
+    use Guzzle\Batch\BatchBuilder;
+
+    $batch = BatchBuilder::factory()
+        ->transferRequests(10)
+        ->build();
+
+Transferring commands
+~~~~~~~~~~~~~~~~~~~~~
+
+The ``Guzzle\Service\Command\BatchCommandTransfer`` class efficiently transfers service commands by grouping commands
+by the client that is used to transfer them.  You can add commands to a batch object that are transferred by different
+clients, and the batch will handle the rest.
+
+.. code-block:: php
+
+    use Guzzle\Batch\BatchBuilder;
+
+    $batch = BatchBuilder::factory()
+        ->transferCommands(10)
+        ->build();
+
+    $batch->add($client->getCommand('foo'))
+        ->add($client->getCommand('baz'))
+        ->add($client->getCommand('bar'));
+
+    $commands = $batch->flush();
+
+Batch behaviors
+---------------
+
+You can add various behaviors to your batch that allow for more customizable transfers.
+
+Automatically flushing a queue
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Use the ``Guzzle\Batch\FlushingBatch`` decorator when you want to pump a large number of items into a batch queue and
+have the queue automatically flush when the size of the queue reaches a certain threshold.
+
+.. code-block:: php
+
+    use Guzzle\Batch\BatchBuilder;
+
+    $batch = BatchBuilder::factory()
+        ->transferRequests(10)
+        ->autoFlushAt(10)
+        ->build();
+
+Batch builder method: ``autoFlushAt($threshold)``
+
+Notifying on flush
+~~~~~~~~~~~~~~~~~~
+
+Use the ``Guzzle\Batch\NotifyingBatch`` decorator if you want a function to be notified each time the batch queue is
+flushed.  This is useful when paired with the flushing batch decorator.  Pass a callable to the ``notify()`` method of
+a batch builder to use this decorator with the builder.
+
+.. code-block:: php
+
+    use Guzzle\Batch\BatchBuilder;
+
+    $batch = BatchBuilder::factory()
+        ->transferRequests(10)
+        ->autoFlushAt(10)
+        ->notify(function (array $transferredItems) {
+            echo 'Transferred ' . count($transferredItems) . "items\n";
+        })
+        ->build();
+
+Batch builder method:: ``notify(callable $callback)``
+
+Keeping a history
+~~~~~~~~~~~~~~~~~
+
+Use the ``Guzzle\Batch\HistoryBatch`` decorator if you want to maintain a history of all the items transferred with
+the batch queue.
+
+.. code-block:: php
+
+    use Guzzle\Batch\BatchBuilder;
+
+    $batch = BatchBuilder::factory()
+        ->transferRequests(10)
+        ->keepHistory()
+        ->build();
+
+After transferring items, you can use the ``getHistory()`` of a batch to retrieve an array of transferred items.  Be
+sure to periodically clear the history using ``clearHistory()``.
+
+Batch builder method: ``keepHistory()``
+
+Exception buffering
+~~~~~~~~~~~~~~~~~~~
+
+Use the ``Guzzle\Batch\ExceptionBufferingBatch`` decorator to buffer exceptions during a transfer so that you can
+transfer as many items as possible then deal with the errored batches after the transfer completes.  After transfer,
+use the ``getExceptions()`` method of a batch to retrieve an array of
+``Guzzle\Batch\Exception\BatchTransferException`` objects.  You can use these exceptions to attempt to retry the
+failed batches.  Be sure to clear the buffered exceptions when you are done with them by using the
+``clearExceptions()`` method.
+
+Batch builder method: ``bufferExceptions()``

+FAQ
+===
+
+What should I do if I get this error: Fatal error: Maximum function nesting level of '100' reached, aborting!
+-------------------------------------------------------------------------------------------------------------
+
+You could run into this error if you have the XDebug extension installed and you execute a lot of requests in
+callbacks.  This error message comes specifically from the XDebug extension. PHP itself does not have a function
+nesting limit. Change this setting in your php.ini to increase the limit::
+
+    xdebug.max_nesting_level = 1000
+
+[`source <http://stackoverflow.com/a/4293870/151504>`_]
+
+How can I speed up my client?
+-----------------------------
+
+There are several things you can do to speed up your client:
+
+1. Utilize a C based HTTP message parser (e.g. ``Guzzle\Parser\Message\PeclHttpMessageParser``)
+2. Disable operation validation by setting the ``command.disable_validation`` option to true on a command
+
+Why am I getting a 417 error response?
+--------------------------------------
+
+This can occur for a number of reasons, but if you are sending PUT, POST, or PATCH requests with an
+``Expect: 100-Continue`` header, a server that does not support this header will return a 417 response. You can work
+around this by calling ``$request->removeHeader('Expect');`` after setting the entity body of a request.

+
+Installing Guzzle
+-----------------
+
+Composer
+~~~~~~~~
+
+The recommended way to install Guzzle is with `Composer <http://getcomposer.org>`_. Composer is a dependency
+management tool for PHP that allows you to declare the dependencies your project needs and installs them into your
+project.
+
+.. code-block:: bash
+
+    # Install Composer
+    curl -sS https://getcomposer.org/installer | php
+
+    # Add Guzzle as a dependency
+    php composer.phar require guzzle/guzzle:~3.9
+
+After installing, you need to require Composer's autoloader:
+
+.. code-block:: php
+
+    require 'vendor/autoload.php';
+
+You can find out more on how to install Composer, configure autoloading, and other best-practices for defining
+dependencies at `getcomposer.org <http://getcomposer.org>`_.
+
+Using only specific parts of Guzzle
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+While you can always just rely on ``guzzle/guzzle``, Guzzle provides several smaller parts of Guzzle as individual
+packages available through Composer.

+
+Bleeding edge
+^^^^^^^^^^^^^
+
+During your development, you can keep up with the latest changes on the master branch by setting the version
+requirement for Guzzle to ``dev-master``.
+
+.. code-block:: js
+
+   {
+      "require": {
+         "guzzle/guzzle": "dev-master"
+      }
+   }
+
+PEAR
+~~~~
+
+Guzzle can be installed through PEAR:
+
+.. code-block:: bash
+
+    pear channel-discover guzzlephp.org/pear
+    pear install guzzle/guzzle
+
+You can install a specific version of Guzzle by providing a version number suffix:
+
+.. code-block:: bash
+
+    pear install guzzle/guzzle-3.9.0
+
+Contributing to Guzzle
+----------------------
+
+In order to contribute, you'll need to checkout the source from GitHub and install Guzzle's dependencies using
+Composer:
+
+.. code-block:: bash
+
+    git clone https://github.com/guzzle/guzzle.git
+    cd guzzle && curl -s http://getcomposer.org/installer | php && ./composer.phar install --dev
+
+Guzzle is unit tested with PHPUnit. You will need to create your own phpunit.xml file in order to run the unit tests
+(or just copy phpunit.xml.dist to phpunit.xml). Run the tests using the vendored PHPUnit binary:
+
+.. code-block:: bash
+
+    vendor/bin/phpunit
+
+You'll need to install node.js v0.5.0 or newer in order to test the cURL implementation.
+

+======================
+The Guzzle HTTP client
+======================
+
+Guzzle gives PHP developers complete control over HTTP requests while utilizing HTTP/1.1 best practices. Guzzle's HTTP
+functionality is a robust framework built on top of the `PHP libcurl bindings <http://www.php.net/curl>`_.
+
+The three main parts of the Guzzle HTTP client are:
+
++--------------+-------------------------------------------------------------------------------------------------------+
+| Clients      | ``Guzzle\Http\Client`` (creates and sends requests, associates a response with a request)             |
++--------------+-------------------------------------------------------------------------------------------------------+
+| Requests     | ``Guzzle\Http\Message\Request`` (requests with no body),                                              |
+|              | ``Guzzle\Http\Message\EntityEnclosingRequest`` (requests with a body)                                 |
++--------------+-------------------------------------------------------------------------------------------------------+
+| Responses    | ``Guzzle\Http\Message\Response``                                                                      |
++--------------+-------------------------------------------------------------------------------------------------------+
+
+Creating a Client
+-----------------
+
+Clients create requests, send requests, and set responses on a request object. When instantiating a client object,
+you can pass an optional "base URL" and optional array of configuration options. A base URL is a
+:doc:`URI template <uri-templates>` that contains the URL of a remote server. When creating requests with a relative
+URL, the base URL of a client will be merged into the request's URL.
+
+.. code-block:: php
+
+    use Guzzle\Http\Client;
+
+    // Create a client and provide a base URL
+    $client = new Client('https://api.github.com');
+
+    $request = $client->get('/user');
+    $request->setAuth('user', 'pass');
+    echo $request->getUrl();
+    // >>> https://api.github.com/user
+
+    // You must send a request in order for the transfer to occur
+    $response = $request->send();
+
+    echo $response->getBody();
+    // >>> {"type":"User", ...
+
+    echo $response->getHeader('Content-Length');
+    // >>> 792
+
+    $data = $response->json();
+    echo $data['type'];
+    // >>> User
+
+Base URLs
+~~~~~~~~~
+
+Notice that the URL provided to the client's ``get()`` method is relative. Relative URLs will always merge into the
+base URL of the client. There are a few rules that control how the URLs are merged.
+
+.. tip::
+
+    Guzzle follows `RFC 3986 <http://tools.ietf.org/html/rfc3986#section-5.2>`_ when merging base URLs and
+    relative URLs.
+
+In the above example, we passed ``/user`` to the ``get()`` method of the client. This is a relative URL, so it will
+merge into the base URL of the client-- resulting in the derived URL of ``https://api.github.com/users``.
+
+``/user`` is a relative URL but uses an absolute path because it contains the leading slash. Absolute paths will
+overwrite any existing path of the base URL. If an absolute path is provided (e.g. ``/path/to/something``), then the
+path specified in the base URL of the client will be replaced with the absolute path, and the query string provided
+by the relative URL will replace the query string of the base URL.
+
+Omitting the leading slash and using relative paths will add to the path of the base URL of the client. So using a
+client base URL of ``https://api.twitter.com/v1.1`` and creating a GET request with ``statuses/user_timeline.json``
+will result in a URL of ``https://api.twitter.com/v1.1/statuses/user_timeline.json``. If a relative path and a query
+string are provided, then the relative path will be appended to the base URL path, and the query string provided will
+be merged into the query string of the base URL.
+
+If an absolute URL is provided (e.g. ``http://httpbin.org/ip``), then the request will completely use the absolute URL
+as-is without merging in any of the URL parts specified in the base URL.
+
+Configuration options
+~~~~~~~~~~~~~~~~~~~~~
+
+The second argument of the client's constructor is an array of configuration data. This can include URI template data
+or special options that alter the client's behavior:
+
++-------------------------------+-------------------------------------------------------------------------------------+
+| ``request.options``           | Associative array of :ref:`Request options <request-options>` to apply to every     |
+|                               | request created by the client.                                                      |
++-------------------------------+-------------------------------------------------------------------------------------+
+| ``redirect.disable``          | Disable HTTP redirects for every request created by the client.                     |
++-------------------------------+-------------------------------------------------------------------------------------+
+| ``curl.options``              | Associative array of cURL options to apply to every request created by the client.  |
+|                               | if either the key or value of an entry in the array is a string, Guzzle will        |
+|                               | attempt to find a matching defined cURL constant automatically (e.g.                |
+|                               | "CURLOPT_PROXY" will be converted to the constant ``CURLOPT_PROXY``).               |
++-------------------------------+-------------------------------------------------------------------------------------+
+| ``ssl.certificate_authority`` | Set to true to use the Guzzle bundled SSL certificate bundle (this is used by       |
+|                               | default, 'system' to use the bundle on your system, a string pointing to a file to  |
+|                               | use a specific certificate file, a string pointing to a directory to use multiple   |
+|                               | certificates, or ``false`` to disable SSL validation (not recommended).             |
+|                               |                                                                                     |
+|                               | When using  Guzzle inside of a phar file, the bundled SSL certificate will be       |
+|                               | extracted to your system's temp folder, and each time a client is created an MD5    |
+|                               | check will be performed to ensure the integrity of the certificate.                 |
++-------------------------------+-------------------------------------------------------------------------------------+
+| ``command.params``            | When using a ``Guzzle\Service\Client`` object, this is an associative array of      |
+|                               | default options to set on each command created by the client.                       |
++-------------------------------+-------------------------------------------------------------------------------------+
+
+Here's an example showing how to set various configuration options, including default headers to send with each request,
+default query string parameters to add to each request, a default auth scheme for each request, and a proxy to use for
+each request. Values can be injected into the client's base URL using variables from the configuration array.
+
+.. code-block:: php
+
+    use Guzzle\Http\Client;
+
+    $client = new Client('https://api.twitter.com/{version}', array(
+        'version'        => 'v1.1',
+        'request.options' => array(
+            'headers' => array('Foo' => 'Bar'),
+            'query'   => array('testing' => '123'),
+            'auth'    => array('username', 'password', 'Basic|Digest|NTLM|Any'),
+            'proxy'   => 'tcp://localhost:80'
+        )
+    ));
+
+Setting a custom User-Agent
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The default Guzzle User-Agent header is ``Guzzle/<Guzzle_Version> curl/<curl_version> PHP/<PHP_VERSION>``. You can
+customize the User-Agent header of a client by calling the ``setUserAgent()`` method of a Client object.
+
+.. code-block:: php
+
+    // Completely override the default User-Agent
+    $client->setUserAgent('Test/123');
+
+    // Prepend a string to the default User-Agent
+    $client->setUserAgent('Test/123', true);
+
+Creating requests with a client
+-------------------------------
+
+A Client object exposes several methods used to create Request objects:
+
+* Create a custom HTTP request: ``$client->createRequest($method, $uri, array $headers, $body, $options)``
+* Create a GET request: ``$client->get($uri, array $headers, $options)``
+* Create a HEAD request: ``$client->head($uri, array $headers, $options)``
+* Create a DELETE request: ``$client->delete($uri, array $headers, $body, $options)``
+* Create a POST request: ``$client->post($uri, array $headers, $postBody, $options)``
+* Create a PUT request: ``$client->put($uri, array $headers, $body, $options)``
+* Create a PATCH request: ``$client->patch($uri, array $headers, $body, $options)``
+
+.. code-block:: php
+
+    use Guzzle\Http\Client;
+
+    $client = new Client('http://baseurl.com/api/v1');
+
+    // Create a GET request using Relative to base URL
+    // URL of the request: http://baseurl.com/api/v1/path?query=123&value=abc)
+    $request = $client->get('path?query=123&value=abc');
+    $response = $request->send();
+
+    // Create HEAD request using a relative URL with an absolute path
+    // URL of the request: http://baseurl.com/path?query=123&value=abc
+    $request = $client->head('/path?query=123&value=abc');
+    $response = $request->send();
+
+    // Create a DELETE request using an absolute URL
+    $request = $client->delete('http://www.example.com/path?query=123&value=abc');
+    $response = $request->send();
+
+    // Create a PUT request using the contents of a PHP stream as the body
+    // Specify custom HTTP headers
+    $request = $client->put('http://www.example.com/upload', array(
+        'X-Header' => 'My Header'
+    ), fopen('http://www.test.com/', 'r'));
+    $response = $request->send();
+
+    // Create a POST request and add the POST files manually
+    $request = $client->post('http://localhost:8983/solr/update')
+        ->addPostFiles(array('file' => '/path/to/documents.xml'));
+    $response = $request->send();
+
+    // Check if a resource supports the DELETE method
+    $supportsDelete = $client->options('/path')->send()->isMethodAllowed('DELETE');
+    $response = $request->send();
+
+Client objects create Request objects using a request factory (``Guzzle\Http\Message\RequestFactoryInterface``).
+You can inject a custom request factory into the Client using ``$client->setRequestFactory()``, but you can typically
+rely on a Client's default request factory.
+
+Static clients
+--------------
+
+You can use Guzzle's static client facade to more easily send simple HTTP requests.
+
+.. code-block:: php
+
+    // Mount the client so that you can access it at \Guzzle
+    Guzzle\Http\StaticClient::mount();
+    $response = Guzzle::get('http://guzzlephp.org');
+
+Each request method of the static client (e.g. ``get()``, ``post()`, ``put()``, etc) accepts an associative array of request
+options to apply to the request.
+
+.. code-block:: php
+
+    $response = Guzzle::post('http://test.com', array(
+        'headers' => array('X-Foo' => 'Bar'),
+        'body'    => array('Test' => '123'),
+        'timeout' => 10
+    ));
+
+.. _request-options:
+
+Request options
+---------------
+
+Request options can be specified when creating a request or in the ``request.options`` parameter of a client. These
+options can control various aspects of a request including: headers to send, query string data, where the response
+should be downloaded, proxies, auth, etc.
+
+headers
+~~~~~~~
+
+Associative array of headers to apply to the request. When specified in the ``$options`` argument of a client creational
+method (e.g. ``get()``, ``post()``, etc), the headers in the ``$options`` array will overwrite headers specified in the
+``$headers`` array.
+
+.. code-block:: php
+
+    $request = $client->get($url, array(), array(
+        'headers' => array('X-Foo' => 'Bar')
+    ));
+
+Headers can be specified on a client to add default headers to every request sent by a client.
+
+.. code-block:: php
+
+    $client = new Guzzle\Http\Client();
+
+    // Set a single header using path syntax
+    $client->setDefaultOption('headers/X-Foo', 'Bar');
+
+    // Set all headers
+    $client->setDefaultOption('headers', array('X-Foo' => 'Bar'));
+
+.. note::
+
+    In addition to setting request options when creating requests or using the ``setDefaultOption()`` method, any
+    default client request option can be set using a client's config object:
+
+    .. code-block:: php
+
+        $client->getConfig()->setPath('request.options/headers/X-Foo', 'Bar');
+
+query
+~~~~~
+
+Associative array of query string parameters to the request. When specified in the ``$options`` argument of a client
+creational method, the query string parameters in the ``$options`` array will overwrite query string parameters
+specified in the `$url`.
+
+.. code-block:: php
+
+    $request = $client->get($url, array(), array(
+        'query' => array('abc' => '123')
+    ));
+
+Query string parameters can be specified on a client to add default query string parameters to every request sent by a
+client.
+
+.. code-block:: php
+
+    $client = new Guzzle\Http\Client();
+
+    // Set a single query string parameter using path syntax
+    $client->setDefaultOption('query/abc', '123');
+
+    // Set an array of default query string parameters
+    $client->setDefaultOption('query', array('abc' => '123'));
+
+body
+~~~~
+
+Sets the body of a request. The value supplied to the body option can be a ``Guzzle\Http\EntityBodyInterface``, string,
+fopen resource, or array when sending POST requests. When a ``body`` request option is supplied, the option value will
+overwrite the ``$body`` argument of a client creational method.
+
+auth
+~~~~
+
+Specifies and array of HTTP authorization parameters parameters to use with the request. The array must contain the
+username in index [0], the password in index [1], and can optionally contain the authentication type in index [2].
+The available authentication types are: "Basic" (default), "Digest", "NTLM", or "Any".
+
+.. code-block:: php
+
+    $request = $client->get($url, array(), array(
+        'auth' => array('username', 'password', 'Digest')
+    ));
+
+    // You can add auth headers to every request of a client
+    $client->setDefaultOption('auth', array('username', 'password', 'Digest'));
+
+cookies
+~~~~~~~
+
+Specifies an associative array of cookies to add to the request.
+
+allow_redirects
+~~~~~~~~~~~~~~~
+
+Specifies whether or not the request should follow redirects. Requests will follow redirects by default. Set
+``allow_redirects`` to ``false`` to disable redirects.
+
+save_to
+~~~~~~~
+
+The ``save_to`` option specifies where the body of a response is downloaded. You can pass the path to a file, an fopen
+resource, or a ``Guzzle\Http\EntityBodyInterface`` object.
+
+See :ref:`Changing where a response is downloaded <request-set-response-body>` for more information on setting the
+`save_to` option.
+
+events
+~~~~~~
+
+The `events` option makes it easy to attach listeners to the various events emitted by a request object. The `events`
+options must be an associative array mapping an event name to a Closure or array the contains a Closure and the
+priority of the event.
+
+.. code-block:: php
+
+    $request = $client->get($url, array(), array(
+        'events' => array(
+            'request.before_send' => function (\Guzzle\Common\Event $e) {
+                echo 'About to send ' . $e['request'];
+            }
+        )
+    ));
+
+    // Using the static client:
+    Guzzle::get($url, array(
+        'events' => array(
+            'request.before_send' => function (\Guzzle\Common\Event $e) {
+                echo 'About to send ' . $e['request'];
+            }
+        )
+    ));
+
+plugins
+~~~~~~~
+
+The `plugins` options makes it easy to attach an array of plugins to a request.
+
+.. code-block:: php
+
+    // Using the static client:
+    Guzzle::get($url, array(
+        'plugins' => array(
+            new Guzzle\Plugin\Cache\CachePlugin(),
+            new Guzzle\Plugin\Cookie\CookiePlugin()
+        )
+    ));
+
+exceptions
+~~~~~~~~~~
+
+The `exceptions` option can be used to disable throwing exceptions for unsuccessful HTTP response codes
+(e.g. 404, 500, etc). Set `exceptions` to false to not throw exceptions.
+
+params
+~~~~~~
+
+The `params` options can be used to specify an associative array of data parameters to add to a request.  Note that
+these are not query string parameters.
+
+timeout / connect_timeout
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+You can specify the maximum number of seconds to allow for an entire transfer to take place before timing out using
+the `timeout` request option. You can specify the maximum number of seconds to wait while trying to connect using the
+`connect_timeout` request option. Set either of these options to 0 to wait indefinitely.
+
+.. code-block:: php
+
+    $request = $client->get('http://www.example.com', array(), array(
+        'timeout'         => 20,
+        'connect_timeout' => 1.5
+    ));
+
+verify
+~~~~~~
+
+Set to true to enable SSL certificate validation (the default), false to disable SSL certificate validation, or supply
+the path to a CA bundle to enable verification using a custom certificate.
+
+cert
+~~~~
+
+The `cert` option lets you specify a PEM formatted SSL client certificate to use with servers that require one. If the
+certificate requires a password, provide an array with the password as the second item.
+
+This would typically be used in conjunction with the `ssl_key` option.
+
+.. code-block:: php
+
+    $request = $client->get('https://www.example.com', array(), array(
+        'cert' => '/etc/pki/client_certificate.pem'
+    )
+
+    $request = $client->get('https://www.example.com', array(), array(
+        'cert' => array('/etc/pki/client_certificate.pem', 's3cr3tp455w0rd')
+    )
+
+ssl_key
+~~~~~~~
+
+The `ssl_key` option lets you specify a file containing your PEM formatted private key, optionally protected by a password.
+Note: your password is sensitive, keep the PHP script containing it safe.
+
+This would typically be used in conjunction with the `cert` option.
+
+.. code-block:: php
+
+    $request = $client->get('https://www.example.com', array(), array(
+        'ssl_key' => '/etc/pki/private_key.pem'
+    )
+
+    $request = $client->get('https://www.example.com', array(), array(
+        'ssl_key' => array('/etc/pki/private_key.pem', 's3cr3tp455w0rd')
+    )
+
+proxy
+~~~~~
+
+The `proxy` option is used to specify an HTTP proxy (e.g. `http://username:password@192.168.16.1:10`).
+
+debug
+~~~~~
+
+The `debug` option is used to show verbose cURL output for a transfer.
+
+stream
+~~~~~~
+
+When using a static client, you can set the `stream` option to true to return a `Guzzle\Stream\Stream` object that can
+be used to pull data from a stream as needed (rather than have cURL download the entire contents of a response to a
+stream all at once).
+
+.. code-block:: php
+
+    $stream = Guzzle::get('http://guzzlephp.org', array('stream' => true));
+    while (!$stream->feof()) {
+        echo $stream->readLine();
+    }
+
+Sending requests
+----------------
+
+Requests can be sent by calling the ``send()`` method of a Request object, but you can also send requests using the
+``send()`` method of a Client.
+
+.. code-block:: php
+
+    $request = $client->get('http://www.amazon.com');
+    $response = $client->send($request);
+
+Sending requests in parallel
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The Client's ``send()`` method accept a single ``Guzzle\Http\Message\RequestInterface`` object or an array of
+RequestInterface objects. When an array is specified, the requests will be sent in parallel.
+
+Sending many HTTP requests serially (one at a time) can cause an unnecessary delay in a script's execution. Each
+request must complete before a subsequent request can be sent. By sending requests in parallel, a pool of HTTP
+requests can complete at the speed of the slowest request in the pool, significantly reducing the amount of time
+needed to execute multiple HTTP requests. Guzzle provides a wrapper for the curl_multi functions in PHP.
+
+Here's an example of sending three requests in parallel using a client object:
+
+.. code-block:: php
+
+    use Guzzle\Common\Exception\MultiTransferException;
+
+    try {
+        $responses = $client->send(array(
+            $client->get('http://www.google.com/'),
+            $client->head('http://www.google.com/'),
+            $client->get('https://www.github.com/')
+        ));
+    } catch (MultiTransferException $e) {
+
+        echo "The following exceptions were encountered:\n";
+        foreach ($e as $exception) {
+            echo $exception->getMessage() . "\n";
+        }
+
+        echo "The following requests failed:\n";
+        foreach ($e->getFailedRequests() as $request) {
+            echo $request . "\n\n";
+        }
+
+        echo "The following requests succeeded:\n";
+        foreach ($e->getSuccessfulRequests() as $request) {
+            echo $request . "\n\n";
+        }
+    }
+
+If the requests succeed, an array of ``Guzzle\Http\Message\Response`` objects are returned. A single request failure
+will not cause the entire pool of requests to fail. Any exceptions thrown while transferring a pool of requests will
+be aggregated into a ``Guzzle\Common\Exception\MultiTransferException`` exception.
+
+Plugins and events
+------------------
+
+Guzzle provides easy to use request plugins that add behavior to requests based on signal slot event notifications
+powered by the
+`Symfony2 Event Dispatcher component <http://symfony.com/doc/2.0/components/event_dispatcher/introduction.html>`_. Any
+event listener or subscriber attached to a Client object will automatically be attached to each request created by the
+client.
+
+Using the same cookie session for each request
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Attach a ``Guzzle\Plugin\Cookie\CookiePlugin`` to a client which will in turn add support for cookies to every request
+created by a client, and each request will use the same cookie session:
+
+.. code-block:: php
+
+    use Guzzle\Plugin\Cookie\CookiePlugin;
+    use Guzzle\Plugin\Cookie\CookieJar\ArrayCookieJar;
+
+    // Create a new cookie plugin
+    $cookiePlugin = new CookiePlugin(new ArrayCookieJar());
+
+    // Add the cookie plugin to the client
+    $client->addSubscriber($cookiePlugin);
+
+.. _client-events:
+
+Events emitted from a client
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+A ``Guzzle\Http\Client`` object emits the following events:
+
++------------------------------+--------------------------------------------+------------------------------------------+
+| Event name                   | Description                                | Event data                               |
++==============================+============================================+==========================================+
+| client.create_request        | Called when a client creates a request     | * client: The client                     |

++------------------------------+--------------------------------------------+------------------------------------------+
+
+.. code-block:: php
+
+    use Guzzle\Common\Event;
+    use Guzzle\Http\Client;
+
+    $client = new Client();
+
+    // Add a listener that will echo out requests as they are created
+    $client->getEventDispatcher()->addListener('client.create_request', function (Event $e) {
+        echo 'Client object: ' . spl_object_hash($e['client']) . "\n";
+        echo "Request object: {$e['request']}\n";
+    });

+===========================
+Request and response bodies
+===========================
+
+`Entity body <http://www.w3.org/Protocols/rfc2616/rfc2616-sec7.html>`_ is the term used for the body of an HTTP
+message. The entity body of requests and responses is inherently a
+`PHP stream <http://php.net/manual/en/book.stream.php>`_ in Guzzle. The body of the request can be either a string or
+a PHP stream which are converted into a ``Guzzle\Http\EntityBody`` object using its factory method. When using a
+string, the entity body is stored in a `temp PHP stream <http://www.php.net/manual/en/wrappers.php.php>`_. The use of
+temp PHP streams helps to protect your application from running out of memory when sending or receiving large entity
+bodies in your messages. When more than 2MB of data is stored in a temp stream, it automatically stores the data on
+disk rather than in memory.
+
+EntityBody objects provide a great deal of functionality: compression, decompression, calculate the Content-MD5,
+calculate the Content-Length (when the resource is repeatable), guessing the Content-Type, and more. Guzzle doesn't
+need to load an entire entity body into a string when sending or retrieving data; entity bodies are streamed when
+being uploaded and downloaded.
+
+Here's an example of gzip compressing a text file then sending the file to a URL:
+
+.. code-block:: php
+
+    use Guzzle\Http\EntityBody;
+
+    $body = EntityBody::factory(fopen('/path/to/file.txt', 'r+'));
+    echo $body->read(1024);
+    $body->seek(0, SEEK_END);
+    $body->write('foo');
+    echo $body->ftell();
+    $body->rewind();
+
+    // Send a request using the body
+    $response = $client->put('http://localhost:8080/uploads', null, $body)->send();
+
+The body of the request can be specified in the ``Client::put()`` or ``Client::post()``  method, or, you can specify
+the body of the request by calling the ``setBody()`` method of any
+``Guzzle\Http\Message\EntityEnclosingRequestInterface`` object.
+
+Compression
+-----------
+
+You can compress the contents of an EntityBody object using the ``compress()`` method. The compress method accepts a
+filter that must match to one of the supported
+`PHP stream filters <http://www.php.net/manual/en/filters.compression.php>`_ on your system (e.g. `zlib.deflate`,
+``bzip2.compress``, etc). Compressing an entity body will stream the entire entity body through a stream compression
+filter into a temporary PHP stream. You can uncompress an entity body using the ``uncompress()`` method and passing
+the PHP stream filter to use when decompressing the stream (e.g. ``zlib.inflate``).
+
+.. code-block:: php
+
+    use Guzzle\Http\EntityBody;
+
+    $body = EntityBody::factory(fopen('/tmp/test.txt', 'r+'));
+    echo $body->getSize();
+    // >>> 1048576
+
+    // Compress using the default zlib.deflate filter
+    $body->compress();
+    echo $body->getSize();
+    // >>> 314572
+
+    // Decompress the stream
+    $body->uncompress();
+    echo $body->getSize();
+    // >>> 1048576
+
+Decorators
+----------
+
+Guzzle provides several EntityBody decorators that can be used to add functionality to an EntityBody at runtime.
+
+IoEmittingEntityBody
+~~~~~~~~~~~~~~~~~~~~
+
+This decorator will emit events when data is read from a stream or written to a stream. Add an event subscriber to the
+entity body's ``body.read`` or ``body.write`` methods to receive notifications when data data is transferred.
+
+.. code-block:: php
+
+    use Guzzle\Common\Event;
+    use Guzzle\Http\EntityBody;
+    use Guzzle\Http\IoEmittingEntityBody;
+
+    $original = EntityBody::factory(fopen('/tmp/test.txt', 'r+'));
+    $body = new IoEmittingEntityBody($original);
+
+    // Listen for read events
+    $body->getEventDispatcher()->addListener('body.read', function (Event $e) {
+        // Grab data from the event
+        $entityBody = $e['body'];
+        // Amount of data retrieved from the body
+        $lengthOfData = $e['length'];
+        // The actual data that was read
+        $data = $e['read'];
+    });
+
+    // Listen for write events
+    $body->getEventDispatcher()->addListener('body.write', function (Event $e) {
+        // Grab data from the event
+        $entityBody = $e['body'];
+        // The data that was written
+        $data = $e['write'];
+        // The actual amount of data that was written
+        $data = $e['read'];
+    });
+
+ReadLimitEntityBody
+~~~~~~~~~~~~~~~~~~~
+
+The ReadLimitEntityBody decorator can be used to transfer a subset or slice of an existing EntityBody object. This can
+be useful for breaking a large file into smaller pieces to be sent in chunks (e.g. Amazon S3's multipart upload API).
+
+.. code-block:: php
+
+    use Guzzle\Http\EntityBody;
+    use Guzzle\Http\ReadLimitEntityBody;
+
+    $original = EntityBody::factory(fopen('/tmp/test.txt', 'r+'));
+    echo $original->getSize();
+    // >>> 1048576
+
+    // Limit the size of the body to 1024 bytes and start reading from byte 2048
+    $body = new ReadLimitEntityBody($original, 1024, 2048);
+    echo $body->getSize();
+    // >>> 1024
+    echo $body->ftell();
+    // >>> 0
+
+CachingEntityBody
+~~~~~~~~~~~~~~~~~
+
+The CachingEntityBody decorator is used to allow seeking over previously read bytes on non-seekable read streams. This
+can be useful when transferring a non-seekable entity body fails due to needing to rewind the stream (for example,
+resulting from a redirect). Data that is read from the remote stream will be buffered in a PHP temp stream so that
+previously read bytes are cached first in memory, then on disk.
+
+.. code-block:: php
+
+    use Guzzle\Http\EntityBody;
+    use Guzzle\Http\CachingEntityBody;
+
+    $original = EntityBody::factory(fopen('http://www.google.com', 'r'));
+    $body = new CachingEntityBody($original);
+
+    $body->read(1024);
+    echo $body->ftell();
+    // >>> 1024
+
+    $body->seek(0);
+    echo $body->ftell();
+    // >>> 0

+HTTP redirects
+==============
+
+By default, Guzzle will automatically follow redirects using the non-RFC compliant implementation used by most web
+browsers. This means that redirects for POST requests are followed by a GET request. You can force RFC compliance by
+enabling the strict mode on a request's parameter object:

+    $request->getParams()->set('redirect.strict', true);
+
+    // You can set globally on a client so all requests use strict redirects
+    $client->getConfig()->set('request.params', array(
+        'redirect.strict' => true
+    ));
+
+By default, Guzzle will redirect up to 5 times before throwing a ``Guzzle\Http\Exception\TooManyRedirectsException``.
+You can raise or lower this value using the ``redirect.max`` parameter of a request object:
+
+.. code-block:: php
+
+    $request->getParams()->set('redirect.max', 2);
+
+Redirect history
+----------------
+
+You can get the number of redirects of a request using the resulting response object's ``getRedirectCount()`` method.
+Similar to cURL's ``effective_url`` property, Guzzle provides the effective URL, or the last redirect URL that returned
+the request, in a response's ``getEffectiveUrl()`` method.
+
+When testing or debugging, it is often useful to see a history of redirects for a particular request. This can be
+achieved using the HistoryPlugin.
+
+.. code-block:: php
+
+    $request = $client->get('/');
+    $history = new Guzzle\Plugin\History\HistoryPlugin();
+    $request->addSubscriber($history);
+    $response = $request->send();
+
+    // Get the last redirect URL or the URL of the request that received
+    // this response
+    echo $response->getEffectiveUrl();
+
+    // Get the number of redirects
+    echo $response->getRedirectCount();
+
+    // Iterate over each sent request and response
+    foreach ($history->getAll() as $transaction) {
+        // Request object
+        echo $transaction['request']->getUrl() . "\n";
+        // Response object
+        echo $transaction['response']->getEffectiveUrl() . "\n";
+    }
+
+    // Or, simply cast the HistoryPlugin to a string to view each request and response
+    echo $history;
+
+Disabling redirects
+-------------------
+
+You can disable redirects on a client by passing a configuration option in the client's constructor:
+
+.. code-block:: php
+
+    $client = new Client(null, array('redirect.disable' => true));
+
+You can also disable redirects per request:
+
+.. code-block:: php
+
+    $request = $client->get($url, array(), array('allow_redirects' => false));
+
+Redirects and non-repeatable streams
+------------------------------------
+
+If you are redirected when sending data from a non-repeatable stream and some of the data has been read off of the
+stream, then you will get a ``Guzzle\Http\Exception\CouldNotRewindStreamException``. You can get around this error by
+adding a custom rewind method to the entity body object being sent in the request.
+
+.. code-block:: php
+
+    $request = $client->post(
+        'http://httpbin.com/redirect/2',
+        null,
+        fopen('http://httpbin.com/get', 'r')
+    );
+
+    // Add a custom function that can be used to rewind the stream
+    // (reopen in this example)
+    $request->getBody()->setRewindFunction(function ($body) {
+        $body->setStream(fopen('http://httpbin.com/get', 'r'));
+        return true;
+    );
+
+    $response = $client->send();

+=====================
+Using Request objects
+=====================
+
+HTTP request messages
+---------------------
+
+Request objects are all about building an HTTP message. Each part of an HTTP request message can be set individually
+using methods on the request object or set in bulk using the ``setUrl()`` method. Here's the format of an HTTP request
+with each part of the request referencing the method used to change it::
+
+    PUT(a) /path(b)?query=123(c) HTTP/1.1(d)
+    X-Header(e): header
+    Content-Length(e): 4
+
+    data(f)
+
++-------------------------+---------------------------------------------------------------------------------+
+| a. **Method**           | The request method can only be set when instantiating a request                 |
++-------------------------+---------------------------------------------------------------------------------+
+| b. **Path**             | ``$request->setPath('/path');``                                                 |
++-------------------------+---------------------------------------------------------------------------------+
+| c. **Query**            | ``$request->getQuery()->set('query', '123');``                                  |
++-------------------------+---------------------------------------------------------------------------------+
+| d. **Protocol version** | ``$request->setProtocolVersion('1.1');``                                        |
++-------------------------+---------------------------------------------------------------------------------+
+| e. **Header**           | ``$request->setHeader('X-Header', 'header');``                                  |
++-------------------------+---------------------------------------------------------------------------------+
+| f. **Entity Body**      |  ``$request->setBody('data'); // Only available with PUT, POST, PATCH, DELETE`` |
++-------------------------+---------------------------------------------------------------------------------+
+
+Creating requests with a client
+-------------------------------
+
+Client objects are responsible for creating HTTP request objects.
+
+GET requests
+~~~~~~~~~~~~
+
+`GET requests <http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html#sec9.3>`_ are the most common form of HTTP
+requests. When you visit a website in your browser, the HTML of the website is downloaded using a GET request. GET
+requests are idempotent requests that are typically used to download content (an entity) identified by a request URL.
+
+.. code-block:: php
+
+    use Guzzle\Http\Client;
+
+    $client = new Client();
+
+    // Create a request that has a query string and an X-Foo header
+    $request = $client->get('http://www.amazon.com?a=1', array('X-Foo' => 'Bar'));
+
+    // Send the request and get the response
+    $response = $request->send();
+
+You can change where the body of a response is downloaded on any request using the
+``$request->setResponseBody(string|EntityBodyInterface|resource)`` method of a request. You can also set the ``save_to``
+option of a request:
+
+.. code-block:: php
+
+    // Send the response body to a file
+    $request = $client->get('http://test.com', array(), array('save_to' => '/path/to/file'));
+
+    // Send the response body to an fopen resource
+    $request = $client->get('http://test.com', array(), array('save_to' => fopen('/path/to/file', 'w')));
+
+HEAD requests
+~~~~~~~~~~~~~
+
+`HEAD requests <http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html#sec9.4>`_ work exactly like GET requests except
+that they do not actually download the response body (entity) of the response message. HEAD requests are useful for
+retrieving meta information about an entity identified by a Request-URI.
+
+.. code-block:: php
+
+    $client = new Guzzle\Http\Client();
+    $request = $client->head('http://www.amazon.com');
+    $response = $request->send();
+    echo $response->getContentLength();
+    // >>> Will output the Content-Length header value
+
+DELETE requests
+~~~~~~~~~~~~~~~
+
+A `DELETE method <http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html#sec9.7>`_ requests that the origin server
+delete the resource identified by the Request-URI.
+
+.. code-block:: php
+
+    $client = new Guzzle\Http\Client();
+    $request = $client->delete('http://example.com');
+    $response = $request->send();
+
+POST requests
+~~~~~~~~~~~~~
+
+While `POST requests <http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html#sec9.5>`_ can be used for a number of
+reasons, POST requests are often used when submitting HTML form data to a website. POST requests can include an entity
+body in the HTTP request.
+
+POST requests in Guzzle are sent with an ``application/x-www-form-urlencoded`` Content-Type header if POST fields are
+present but no files are being sent in the POST. If files are specified in the POST request, then the Content-Type
+header will become ``multipart/form-data``.
+
+The ``post()`` method of a client object accepts four arguments: the URL, optional headers, post fields, and an array of
+request options. To send files in the POST request, prepend the ``@`` symbol to the array value (just like you would if
+you were using the PHP ``curl_setopt`` function).
+
+Here's how to create a multipart/form-data POST request containing files and fields:
+
+.. code-block:: php
+
+    $request = $client->post('http://httpbin.org/post', array(), array(
+        'custom_field' => 'my custom value',
+        'file_field'   => '@/path/to/file.xml'
+    ));
+
+    $response = $request->send();
+
+.. note::
+
+    Remember to **always** sanitize user input when sending POST requests:
+
+    .. code-block:: php
+
+        // Prevent users from accessing sensitive files by sanitizing input
+        $_POST = array('firstname' => '@/etc/passwd');
+        $request = $client->post('http://www.example.com', array(), array (
+            'firstname' => str_replace('@', '', $_POST['firstname'])
+        ));
+
+You can alternatively build up the contents of a POST request.
+
+.. code-block:: php
+
+    $request = $client->post('http://httpbin.org/post')
+        ->setPostField('custom_field', 'my custom value')
+        ->addPostFile('file', '/path/to/file.xml');
+
+    $response = $request->send();
+
+Raw POST data
+^^^^^^^^^^^^^
+
+POST requests can also contain raw POST data that is not related to HTML forms.
+
+.. code-block:: php
+
+    $request = $client->post('http://httpbin.org/post', array(), 'this is the body');
+    $response = $request->send();
+
+You can set the body of POST request using the ``setBody()`` method of the
+``Guzzle\Http\Message\EntityEnclosingRequest`` object. This method accepts a string, a resource returned from
+``fopen``, or a ``Guzzle\Http\EntityBodyInterface`` object.
+
+.. code-block:: php
+
+    $request = $client->post('http://httpbin.org/post');
+    // Set the body of the POST to stream the contents of /path/to/large_body.txt
+    $request->setBody(fopen('/path/to/large_body.txt', 'r'));
+    $response = $request->send();
+
+PUT requests
+~~~~~~~~~~~~
+
+The `PUT method <http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html#sec9.6>`_ requests that the enclosed entity be
+stored under the supplied Request-URI. PUT requests are similar to POST requests in that they both can send an entity
+body in the request message.
+
+The body of a PUT request (any any ``Guzzle\Http\Message\EntityEnclosingRequestInterface`` object) is always stored as
+a ``Guzzle\Http\Message\EntityBodyInterface`` object. This allows a great deal of flexibility when sending data to a
+remote server. For example, you can stream the contents of a stream returned by fopen, stream the contents of a
+callback function, or simply send a string of data.
+
+.. code-block:: php
+
+    $request = $client->put('http://httpbin.org/put', array(), 'this is the body');
+    $response = $request->send();
+
+Just like with POST, PATH, and DELETE requests, you can set the body of a PUT request using the ``setBody()`` method.
+
+.. code-block:: php
+
+    $request = $client->put('http://httpbin.org/put');
+    $request->setBody(fopen('/path/to/large_body.txt', 'r'));
+    $response = $request->send();
+
+PATCH requests
+~~~~~~~~~~~~~~
+
+`PATCH requests <http://tools.ietf.org/html/rfc5789>`_ are used to modify a resource.
+
+.. code-block:: php
+
+    $request = $client->patch('http://httpbin.org', array(), 'this is the body');
+    $response = $request->send();
+
+OPTIONS requests
+~~~~~~~~~~~~~~~~
+
+The `OPTIONS method <http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html#sec9.2>`_ represents a request for
+information about the communication options available on the request/response chain identified by the Request-URI.
+
+.. code-block:: php
+
+    $request = $client->options('http://httpbin.org');
+    $response = $request->send();
+
+    // Check if the PUT method is supported by this resource
+    var_export($response->isMethodAllows('PUT'));
+
+Custom requests
+~~~~~~~~~~~~~~~
+
+You can create custom HTTP requests that use non-standard HTTP methods using the ``createRequest()`` method of a
+client object.
+
+.. code-block:: php
+
+    $request = $client->createRequest('COPY', 'http://example.com/foo', array(
+        'Destination' => 'http://example.com/bar',
+        'Overwrite'   => 'T'
+    ));
+    $response = $request->send();
+
+Query string parameters
+-----------------------
+
+Query string parameters of a request are owned by a request's ``Guzzle\Http\Query`` object that is accessible by
+calling ``$request->getQuery()``. The Query class extends from ``Guzzle\Common\Collection`` and allows you to set one
+or more query string parameters as key value pairs. You can set a parameter on a Query object using the
+``set($key, $value)`` method or access the query string object like an associative array. Any previously specified
+value for a key will be overwritten when using ``set()``. Use ``add($key, $value)`` to add a value to query string
+object, and in the event of a collision with an existing value at a specific key, the value will be converted to an
+array that contains all of the previously set values.
+
+.. code-block:: php
+
+    $request = new Guzzle\Http\Message\Request('GET', 'http://www.example.com?foo=bar&abc=123');
+
+    $query = $request->getQuery();
+    echo "{$query}\n";
+    // >>> foo=bar&abc=123
+
+    $query->remove('abc');
+    echo "{$query}\n";
+    // >>> foo=bar
+
+    $query->set('foo', 'baz');
+    echo "{$query}\n";
+    // >>> foo=baz
+
+    $query->add('foo', 'bar');
+    echo "{$query}\n";
+    // >>> foo%5B0%5D=baz&foo%5B1%5D=bar
+
+Whoah! What happened there? When ``foo=bar`` was added to the existing ``foo=baz`` query string parameter, the
+aggregator associated with the Query object was used to help convert multi-value query string parameters into a string.
+Let's disable URL-encoding to better see what's happening.
+
+.. code-block:: php
+
+    $query->useUrlEncoding(false);
+    echo "{$query}\n";
+    // >>> foo[0]=baz&foo[1]=bar
+
+.. note::
+
+    URL encoding can be disabled by passing false, enabled by passing true, set to use RFC 1738 by passing
+    ``Query::FORM_URLENCODED`` (internally uses PHP's ``urlencode`` function), or set to RFC 3986 by passing
+    ``Query::RFC_3986`` (this is the default and internally uses PHP's ``rawurlencode`` function).
+
+As you can see, the multiple values were converted into query string parameters following the default PHP convention of
+adding numerically indexed square bracket suffixes to each key (``foo[0]=baz&foo[1]=bar``). The strategy used to convert
+multi-value parameters into a string can be customized using the ``setAggregator()`` method of the Query class. Guzzle
+ships with the following query string aggregators by default:
+
+1. ``Guzzle\Http\QueryAggregator\PhpAggregator``: Aggregates using PHP style brackets (e.g. ``foo[0]=baz&foo[1]=bar``)
+2. ``Guzzle\Http\QueryAggregator\DuplicateAggregator``: Performs no aggregation and allows for key value pairs to be
+   repeated in a URL (e.g. ``foo=baz&foo=bar``)
+3. ``Guzzle\Http\QueryAggregator\CommaAggregator``: Aggregates using commas (e.g. ``foo=baz,bar``)
+
+.. _http-message-headers:
+
+HTTP Message Headers
+--------------------
+
+HTTP message headers are case insensitive, multiple occurrences of any header can be present in an HTTP message
+(whether it's valid or not), and some servers require specific casing of particular headers. Because of this, request
+and response headers are stored in ``Guzzle\Http\Message\Header`` objects. The Header object can be cast as a string,
+counted, or iterated to retrieve each value from the header. Casting a Header object to a string will return all of
+the header values concatenated together using a glue string (typically ", ").
+
+A request (and response) object have several methods that allow you to retrieve and modify headers.
+
+* ``getHeaders()``: Get all of the headers of a message as a ``Guzzle\Http\Message\Header\HeaderCollection`` object.
+* ``getHeader($header)``: Get a specific header from a message. If the header exists, you'll get a
+  ``Guzzle\Http\Message\Header`` object. If the header does not exist, this methods returns ``null``.
+* ``hasHeader($header)``: Returns true or false based on if the message has a particular header.
+* ``setHeader($header, $value)``: Set a header value and overwrite any previously set value for this header.
+* ``addHeader($header, $value)``: Add a header with a particular name. If a previous value was already set by the same,
+  then the header will contain multiple values.
+* ``removeHeader($header)``: Remove a header by name from the message.
+
+.. code-block:: php
+
+    $request = new Request('GET', 'http://httpbin.com/cookies');
+    // addHeader will set and append to any existing header values
+    $request->addHeader('Foo', 'bar');
+    $request->addHeader('foo', 'baz');
+    // setHeader overwrites any existing values
+    $request->setHeader('Test', '123');
+
+    // Request headers can be cast as a string
+    echo $request->getHeader('Foo');
+    // >>> bar, baz
+    echo $request->getHeader('Test');
+    // >>> 123
+
+    // You can count the number of headers of a particular case insensitive name
+    echo count($request->getHeader('foO'));
+    // >>> 2
+
+    // You can iterate over Header objects
+    foreach ($request->getHeader('foo') as $header) {
+        echo $header . "\n";
+    }
+
+    // You can get all of the request headers as a Guzzle\Http\Message\Header\HeaderCollection object
+    $headers = $request->getHeaders();
+
+    // Missing headers return NULL
+    var_export($request->getHeader('Missing'));
+    // >>> null
+
+    // You can see all of the different variations of a header by calling raw() on the Header
+    var_export($request->getHeader('foo')->raw());
+
+Setting the body of a request
+-----------------------------
+
+Requests that can send a body (e.g. PUT, POST, DELETE, PATCH) are instances of
+``Guzzle\Http\Message\EntityEnclosingRequestInterface``. Entity enclosing requests contain several methods that allow
+you to specify the body to send with a request.
+
+Use the ``setBody()`` method of a request to set the body that will be sent with a request. This method accepts a
+string, a resource returned by ``fopen()``, an array, or an instance of ``Guzzle\Http\EntityBodyInterface``. The body
+will then be streamed from the underlying ``EntityBodyInterface`` object owned by the request. When setting the body
+of the request, you can optionally specify a Content-Type header and whether or not to force the request to use
+chunked Transfer-Encoding.
+
+.. code-block:: php
+
+    $request = $client->put('/user.json');
+    $request->setBody('{"foo":"baz"}', 'application/json');
+
+Content-Type header
+~~~~~~~~~~~~~~~~~~~
+
+Guzzle will automatically add a Content-Type header to a request if the Content-Type can be guessed based on the file
+extension of the payload being sent or the file extension present in the path of a request.
+
+.. code-block:: php
+
+    $request = $client->put('/user.json', array(), '{"foo":"bar"}');
+    // The Content-Type was guessed based on the path of the request
+    echo $request->getHeader('Content-Type');
+    // >>> application/json
+
+    $request = $client->put('/user.json');
+    $request->setBody(fopen('/tmp/user_data.json', 'r'));
+    // The Content-Type was guessed based on the path of the entity body
+    echo $request->getHeader('Content-Type');
+    // >>> application/json
+
+Transfer-Encoding: chunked header
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+When sending HTTP requests that contain a payload, you must let the remote server know how to determine when the entire
+message has been sent. This usually is done by supplying a ``Content-Length`` header that tells the origin server the
+size of the body that is to be sent. In some cases, the size of the payload being sent in a request cannot be known
+before initiating the transfer. In these cases (when using HTTP/1.1), you can use the ``Transfer-Encoding: chunked``
+header.
+
+If the Content-Length cannot be determined (i.e. using a PHP ``http://`` stream), then Guzzle will automatically add
+the ``Transfer-Encoding: chunked`` header to the request.
+
+.. code-block:: php
+
+    $request = $client->put('/user.json');
+    $request->setBody(fopen('http://httpbin.org/get', 'r'));
+
+    // The Content-Length could not be determined
+    echo $request->getHeader('Transfer-Encoding');
+    // >>> chunked
+
+See :doc:`/http-client/entity-bodies` for more information on entity bodies.
+
+Expect: 100-Continue header
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The ``Expect: 100-Continue`` header is used to help a client prevent sending a large payload to a server that will
+reject the request. This allows clients to fail fast rather than waste bandwidth sending an erroneous payload. Guzzle
+will automatically add the ``Expect: 100-Continue`` header to a request when the size of the payload exceeds 1MB or if
+the body of the request is not seekable (this helps to prevent errors when a non-seekable body request is redirected).
+
+.. note::
+
+    If you find that your larger requests are taking too long to complete, you should first check if the
+    ``Expect: 100-Continue`` header is being sent with the request. Some servers do not respond well to this header,
+    which causes cURL to sleep for `1 second <http://curl.haxx.se/mail/lib-2010-01/0182.html>`_.
+
+POST fields and files
+~~~~~~~~~~~~~~~~~~~~~
+
+Any entity enclosing request can send POST style fields and files. This includes POST, PUT, PATCH, and DELETE requests.
+Any request that has set POST fields or files will use cURL's POST message functionality.
+
+.. code-block:: php
+
+    $request = $client->post('/post');
+    // Set an overwrite any previously specified value
+    $request->setPostField('foo', 'bar');
+    // Append a value to any existing values
+    $request->getPostFields()->add('foo', 'baz');
+    // Remove a POST field by name
+    $request->removePostField('fizz');
+
+    // Add a file to upload (forces multipart/form-data)
+    $request->addPostFile('my_file', '/path/to/file', 'plain/text');
+    // Remove a POST file by POST key name
+    $request->removePostFile('my_other_file');
+
+.. tip::
+
+    Adding a large number of POST fields to a POST request is faster if you use the ``addPostFields()`` method so that
+    you can add and process multiple fields with a single call. Adding multiple POST files is also faster using
+    ``addPostFiles()``.
+
+Working with cookies
+--------------------
+
+Cookies can be modified and retrieved from a request using the following methods:
+
+.. code-block:: php
+
+    $request->addCookie($name, $value);
+    $request->removeCookie($name);
+    $value = $request->getCookie($name);
+    $valueArray = $request->getCookies();
+
+Use the :doc:`cookie plugin </plugins/cookie-plugin>` if you need to reuse cookies between requests.
+
+.. _request-set-response-body:
+
+Changing where a response is downloaded
+----------------------------------------
+
+When a request is sent, the body of the response will be stored in a PHP temp stream by default. You can change the
+location in which the response will be downloaded using ``$request->setResponseBody($body)`` or the ``save_to`` request
+option. This can be useful for downloading the contents of a URL to a specific file.
+
+Here's an example of using request options:
+
+.. code-block:: php
+
+    $request = $this->client->get('http://example.com/large.mov', array(), array(
+        'save_to' => '/tmp/large_file.mov'
+    ));
+    $request->send();
+    var_export(file_exists('/tmp/large_file.mov'));
+    // >>> true
+
+Here's an example of using ``setResponseBody()``:
+
+.. code-block:: php
+
+    $body = fopen('/tmp/large_file.mov', 'w');
+    $request = $this->client->get('http://example.com/large.mov');
+    $request->setResponseBody($body);
+
+    // You can more easily specify the name of a file to save the contents
+    // of the response to by passing a string to ``setResponseBody()``.
+
+    $request = $this->client->get('http://example.com/large.mov');
+    $request->setResponseBody('/tmp/large_file.mov');
+
+Custom cURL options
+-------------------
+
+Most of the functionality implemented in the libcurl bindings has been simplified and abstracted by Guzzle. Developers
+who need access to `cURL specific functionality <http://www.php.net/curl_setopt>`_ can still add cURL handle
+specific behavior to Guzzle HTTP requests by modifying the cURL options collection of a request:
+
+.. code-block:: php
+
+    $request->getCurlOptions()->set(CURLOPT_LOW_SPEED_LIMIT, 200);
+
+Other special options that can be set in the ``curl.options`` array include:
+
++-------------------------+---------------------------------------------------------------------------------+
+| debug                   | Adds verbose cURL output to a temp stream owned by the cURL handle object       |
++-------------------------+---------------------------------------------------------------------------------+
+| progress                | Instructs cURL to emit events when IO events occur. This allows you to be       |
+|                         | notified when bytes are transferred over the wire by subscribing to a request's |
+|                         | ``curl.callback.read``, ``curl.callback.write``, and ``curl.callback.progress`` |
+|                         | events.                                                                         |
++-------------------------+---------------------------------------------------------------------------------+
+
+Request options
+---------------
+
+Requests options can be specified when creating a request or in the ``request.options`` parameter of a client. These
+options can control various aspects of a request including: headers to send, query string data, where the response
+should be downloaded, proxies, auth, etc.
+
+.. code-block:: php
+
+    $request = $client->get($url, $headers, array('proxy' => 'http://proxy.com'));
+
+See :ref:`Request options <request-options>` for more information.
+
+Working with errors
+-------------------
+
+HTTP errors
+~~~~~~~~~~~
+
+Requests that receive a 4xx or 5xx response will throw a ``Guzzle\Http\Exception\BadResponseException``. More
+specifically, 4xx errors throw a ``Guzzle\Http\Exception\ClientErrorResponseException``, and 5xx errors throw a
+``Guzzle\Http\Exception\ServerErrorResponseException``. You can catch the specific exceptions or just catch the
+BadResponseException to deal with either type of error. Here's an example of catching a generic BadResponseException:
+
+.. code-block:: php
+
+    try {
+        $response = $client->get('/not_found.xml')->send();
+    } catch (Guzzle\Http\Exception\BadResponseException $e) {
+        echo 'Uh oh! ' . $e->getMessage();
+        echo 'HTTP request URL: ' . $e->getRequest()->getUrl() . "\n";
+        echo 'HTTP request: ' . $e->getRequest() . "\n";
+        echo 'HTTP response status: ' . $e->getResponse()->getStatusCode() . "\n";
+        echo 'HTTP response: ' . $e->getResponse() . "\n";
+    }
+
+Throwing an exception when a 4xx or 5xx response is encountered is the default behavior of Guzzle requests. This
+behavior can be overridden by adding an event listener with a higher priority than -255 that stops event propagation.
+You can subscribe to ``request.error`` to receive notifications any time an unsuccessful response is received.
+
+You can change the response that will be associated with the request by calling ``setResponse()`` on the
+``$event['request']`` object passed into your listener, or by changing the ``$event['response']`` value of the
+``Guzzle\Common\Event`` object that is passed to your listener. Transparently changing the response associated with a
+request by modifying the event allows you to retry failed requests without complicating the code that uses the client.
+This might be useful for sending requests to a web service that has expiring auth tokens. When a response shows that
+your token has expired, you can get a new token, retry the request with the new token, and return the successful
+response to the user.
+
+Here's an example of retrying a request using updated authorization credentials when a 401 response is received,
+overriding the response of the original request with the new response, and still allowing the default exception
+behavior to be called when other non-200 response status codes are encountered:
+
+.. code-block:: php
+
+    // Add custom error handling to any request created by this client
+    $client->getEventDispatcher()->addListener('request.error', function(Event $event) {
+
+        if ($event['response']->getStatusCode() == 401) {
+
+            $newRequest = $event['request']->clone();
+            $newRequest->setHeader('X-Auth-Header', MyApplication::getNewAuthToken());
+            $newResponse = $newRequest->send();
+
+            // Set the response object of the request without firing more events
+            $event['response'] = $newResponse;
+
+            // You can also change the response and fire the normal chain of
+            // events by calling $event['request']->setResponse($newResponse);
+
+            // Stop other events from firing when you override 401 responses
+            $event->stopPropagation();
+        }
+
+    });
+
+cURL errors
+~~~~~~~~~~~
+
+Connection problems and cURL specific errors can also occur when transferring requests using Guzzle. When Guzzle
+encounters cURL specific errors while transferring a single request, a ``Guzzle\Http\Exception\CurlException`` is
+thrown with an informative error message and access to the cURL error message.
+
+A ``Guzzle\Http\Exception\MultiTransferException`` exception is thrown when a cURL specific error occurs while
+transferring multiple requests in parallel. You can then iterate over all of the exceptions encountered during the
+transfer.
+
+Plugins and events
+------------------
+
+Guzzle request objects expose various events that allow you to hook in custom logic. A request object owns a
+``Symfony\Component\EventDispatcher\EventDispatcher`` object that can be accessed by calling
+``$request->getEventDispatcher()``. You can use the event dispatcher to add listeners (a simple callback function) or
+event subscribers (classes that listen to specific events of a dispatcher). You can add event subscribers to a request
+directly by just calling ``$request->addSubscriber($mySubscriber);``.
+
+.. _request-events:
+
+Events emitted from a request
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+A ``Guzzle\Http\Message\Request`` and ``Guzzle\Http\Message\EntityEnclosingRequest`` object emit the following events:
+

+======================
+Using Response objects
+======================
+
+Sending a request will return a ``Guzzle\Http\Message\Response`` object. You can view the raw  HTTP response message by
+casting the Response object to a string. Casting the response to a string will return the entity body of the response
+as a string too, so this might be an expensive operation if the entity body is stored in a file or network stream. If
+you only want to see the response headers, you can call ``getRawHeaders()``.
+
+Response status line
+--------------------
+
+The different parts of a response's `status line <http://www.w3.org/Protocols/rfc2616/rfc2616-sec6.html#sec6.1>`_
+(the first line of the response HTTP message) are easily retrievable.
+
+.. code-block:: php
+
+    $response = $client->get('http://www.amazon.com')->send();
+
+    echo $response->getStatusCode();      // >>> 200
+    echo $response->getReasonPhrase();    // >>> OK
+    echo $response->getProtocol();        // >>> HTTP
+    echo $response->getProtocolVersion(); // >>> 1.1
+
+You can determine the type of the response using several helper methods:
+
+.. code-block:: php
+
+    $response->isSuccessful(); // true
+    $response->isInformational();
+    $response->isRedirect();
+    $response->isClientError();
+    $response->isServerError();
+
+Response headers
+----------------
+
+The Response object contains helper methods for retrieving common response headers. These helper methods normalize the
+variations of HTTP response headers.
+
+.. code-block:: php
+
+    $response->getCacheControl();
+    $response->getContentType();
+    $response->getContentLength();
+    $response->getContentEncoding();
+    $response->getContentMd5();
+    $response->getEtag();
+    // etc... There are methods for every known response header
+
+You can interact with the Response headers using the same exact methods used to interact with Request headers. See
+:ref:`http-message-headers` for more information.
+
+.. code-block:: php
+
+    echo $response->getHeader('Content-Type');
+    echo $response->getHeader('Content-Length');
+    echo $response->getHeaders()['Content-Type']; // PHP 5.4
+
+Response body
+-------------
+
+The entity body object of a response can be retrieved by calling ``$response->getBody()``. The response EntityBody can
+be cast to a string, or you can pass ``true`` to this method to retrieve the body as a string.
+
+.. code-block:: php
+
+    $request = $client->get('http://www.amazon.com');
+    $response = $request->send();
+    echo $response->getBody();
+
+See :doc:`/http-client/entity-bodies` for more information on entity bodies.
+
+JSON Responses
+~~~~~~~~~~~~~~
+
+You can easily parse and use a JSON response as an array using the ``json()`` method of a response. This method will
+always return an array if the response is valid JSON or if the response body is empty. You will get an exception if you
+call this method and the response is not valid JSON.
+
+.. code-block:: php
+
+    $data = $response->json();
+    echo gettype($data);
+    // >>> array
+
+XML Responses
+~~~~~~~~~~~~~
+
+You can easily parse and use a XML response as SimpleXMLElement object using the ``xml()`` method of a response. This
+method will always return a SimpleXMLElement object if the response is valid XML or if the response body is empty. You
+will get an exception if you call this method and the response is not valid XML.
+
+.. code-block:: php
+
+    $xml = $response->xml();
+    echo $xml->foo;
+    // >>> Bar!
+
+Streaming responses
+-------------------
+
+Some web services provide streaming APIs that allow a client to keep a HTTP request open for an extended period of
+time while polling and reading. Guzzle provides a simple way to convert HTTP request messages into
+``Guzzle\Stream\Stream`` objects so that you can send the initial headers of a request, read the response headers, and
+pull in the response body manually as needed.
+
+Here's an example using the Twitter Streaming API to track the keyword "bieber":
+
+.. code-block:: php
+
+    use Guzzle\Http\Client;
+    use Guzzle\Stream\PhpStreamRequestFactory;
+
+    $client = new Client('https://stream.twitter.com/1');
+
+    $request = $client->post('statuses/filter.json', null, array(
+        'track' => 'bieber'
+    ));
+
+    $request->setAuth('myusername', 'mypassword');
+
+    $factory = new PhpStreamRequestFactory();
+    $stream = $factory->fromRequest($request);
+
+    // Read until the stream is closed
+    while (!$stream->feof()) {
+        // Read a line from the stream
+        $line = $stream->readLine();
+        // JSON decode the line of data
+        $data = json_decode($line, true);
+    }
+
+You can use the ``stream`` request option when using a static client to more easily create a streaming response.
+
+.. code-block:: php
+
+    $stream = Guzzle::get('http://guzzlephp.org', array('stream' => true));
+    while (!$stream->feof()) {
+        echo $stream->readLine();
+    }

+URI templates
+=============
+
+The ``$uri`` passed to one of the client's request creational methods or the base URL of a client can utilize URI
+templates. Guzzle supports the entire `URI templates RFC <http://tools.ietf.org/html/rfc6570>`_. URI templates add a
+special syntax to URIs that replace template place holders with user defined variables.
+
+Every request created by a Guzzle HTTP client passes through a URI template so that URI template expressions are
+automatically expanded:
+
+.. code-block:: php
+
+    $client = new Guzzle\Http\Client('https://example.com/', array('a' => 'hi'));
+    $request = $client->get('/{a}');
+
+Because of URI template expansion, the URL of the above request will become ``https://example.com/hi``. Notice that
+the template was expanded using configuration variables of the client. You can pass in custom URI template variables
+by passing the URI of your request as an array where the first index of the array is the URI template and the second
+index of the array are template variables that are merged into the client's configuration variables.
+
+.. code-block:: php
+
+    $request = $client->get(array('/test{?a,b}', array('b' => 'there')));
+
+The URL for this request will become ``https://test.com?a=hi&b=there``. URI templates aren't limited to just simple
+variable replacements;  URI templates can provide an enormous amount of flexibility when creating request URIs.
+
+.. code-block:: php
+
+    $request = $client->get(array('http://example.com{+path}{/segments*}{?query,data*}', array(
+        'path'     => '/foo/bar',
+        'segments' => array('one', 'two'),
+        'query'    => 'test',
+        'data'     => array(
+            'more' => 'value'
+        )
+    )));
+
+The resulting URL would become ``http://example.com/foo/bar/one/two?query=test&more=value``.
+
+By default, URI template expressions are enclosed in an opening and closing brace (e.g. ``{var}``). If you are working
+with a web service that actually uses braces (e.g. Solr), then you can specify a custom regular expression to use to
+match URI template expressions.
+
+.. code-block:: php
+
+    $client->getUriTemplate()->setRegex('/\<\$(.+)\>/');
+    $client->get('/<$a>');
+
+You can learn about all of the different features of URI templates by reading the
+`URI templates RFC <http://tools.ietf.org/html/rfc6570>`_.

+Guzzle iterators
+================
+
+Guzzle provides several SPL iterators that can be used with other SPL iterators, including Guzzle resource iterators.
+Guzzle's ``guzzle/iterator`` component can also be used independently of the rest of Guzzle through Packagist and
+Composer: https://packagist.org/packages/guzzle/iterator
+
+ChunkedIterator
+---------------
+
+Pulls out multiple values from an inner iterator and yields and array of values for each outer iteration -- essentially
+pulling out chunks of values from the inner iterator.
+
+.. code-block:: php
+
+    use Guzzle\Iterator\ChunkedIterator;
+
+    $inner = new ArrayIterator(range(0, 8));
+    $chunkedIterator = new ChunkedIterator($inner, 2);
+
+    foreach ($chunkedIterator as $chunk) {
+        echo implode(', ', $chunk) . "\n";
+    }
+
+    // >>> 0, 1
+    // >>> 2, 3
+    // >>> 4, 5
+    // >>> 6, 7
+    // >>> 8
+
+FilterIterator
+--------------
+
+This iterator is used to filter values out of the inner iterator. This iterator can be used when PHP 5.4's
+CallbackFilterIterator is not available.
+
+.. code-block:: php
+
+    use Guzzle\Iterator\FilterIterator;
+
+    $inner = new ArrayIterator(range(1, 10));
+    $filterIterator = new FilterIterator($inner, function ($value) {

+    }
+
+    // >>> 2
+    // >>> 4
+    // >>> 6
+    // >>> 8
+    // >>> 10
+
+MapIterator
+-----------
+
+This iterator modifies the values of the inner iterator before yielding.
+
+.. code-block:: php
+
+    use Guzzle\Iterator\MapIterator;
+
+    $inner = new ArrayIterator(range(0, 3));
+
+    $mapIterator = new MapIterator($inner, function ($value) {

+    }
+
+    // >>> 0
+    // >>> 10
+    // >>> 20
+    // >>> 30
+
+MethodProxyIterator
+-------------------
+
+This decorator is useful when you need to expose a specific method from an inner iterator that might be wrapper
+by one or more iterator decorators. This decorator proxies missing method calls to each inner iterator until one
+of the inner iterators can fulfill the call.
+

+Resource iterators
+==================
+
+Web services often implement pagination in their responses which requires the end-user to issue a series of consecutive
+requests in order to fetch all of the data they asked for. Users of your web service client should not be responsible
+for implementing the logic involved in iterating through pages of results. Guzzle provides a simple resource iterator
+foundation to make it easier on web service client developers to offer a useful abstraction layer.
+
+Getting an iterator from a client
+---------------------------------
+
+    ResourceIteratorInterface Guzzle\Service\Client::getIterator($command [, array $commandOptions, array $iteratorOptions ])
+
+The ``getIterator`` method of a ``Guzzle\Service\ClientInterface`` object provides a convenient interface for
+instantiating a resource iterator for a specific command. This method implicitly uses a
+``Guzzle\Service\Resource\ResourceIteratorFactoryInterface`` object to create resource iterators. Pass an
+instantiated command object or the name of a command in the first argument. When passing the name of a command, the
+command factory of the client will create the command by name using the ``$commandOptions`` array. The third argument
+may be used to pass an array of options to the constructor of the instantiated ``ResourceIteratorInterface`` object.
+
+.. code-block:: php
+
+    $iterator = $client->getIterator('get_users');
+
+    foreach ($iterator as $user) {
+        echo $user['name'] . ' age ' . $user['age'] . PHP_EOL;
+    }
+
+The above code sample might execute a single request or a thousand requests. As a consumer of a web service, I don't
+care. I just want to iterate over all of the users.
+
+Iterator options
+~~~~~~~~~~~~~~~~
+
+The two universal options that iterators should support are ``limit`` and ``page_size``. Using the ``limit`` option
+tells the resource iterator to attempt to limit the total number of iterated resources to a specific amount. Keep in
+mind that this is not always possible due to limitations that may be inherent to a web service. The ``page_size``
+option is used to tell a resource iterator how many resources to request per page of results. Much like the ``limit``
+option, you can not rely on getting back exactly the number of resources your specify in the ``page_size`` option.
+
+.. note::
+
+    The ``limit`` and ``page_size`` options can also be specified on an iterator using the ``setLimit($limit)`` and
+    ``setPageSize($pageSize)`` methods.
+
+Resolving iterator class names
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The default resource iterator factory of a client object expects that your iterators are stored under the ``Model``
+folder of your client and that an iterator is names after the CamelCase name of a command followed by the word
+"Iterator". For example, if you wanted to create an iterator for the ``get_users`` command, then your iterator class
+would be ``Model\GetUsersIterator`` and would be stored in ``Model/GetUsersIterator.php``.
+
+Creating an iterator
+--------------------
+
+While not required, resource iterators in Guzzle typically iterate using a ``Guzzle\Service\Command\CommandInterface``
+object. ``Guzzle\Service\Resource\ResourceIterator``, the default iterator implementation that you should extend,
+accepts a command object and array of iterator options in its constructor. The command object passed to the resource
+iterator is expected to be ready to execute and not previously executed. The resource iterator keeps a reference of
+this command and clones the original command each time a subsequent request needs to be made to fetch more data.
+
+Implement the sendRequest method
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The most important thing (and usually the only thing) you need to do when creating a resource iterator is to implement
+the ``sendRequest()`` method of the resource iterator. The ``sendRequest()`` method is called when you begin
+iterating or if there are no resources left to iterate and it you expect to retrieve more resources by making a
+subsequent request. The ``$this->command`` property of the resource iterator is updated with a cloned copy of the
+original command object passed into the constructor of the iterator. Use this command object to issue your subsequent
+requests.
+
+The ``sendRequest()`` method must return an array of the resources you retrieved from making the subsequent call.
+Returning an empty array will stop the iteration. If you suspect that your web service client will occasionally return
+an empty result set but still requires further iteration, then you must implement a sort of loop in your
+``sendRequest()`` method that will continue to issue subsequent requests until your reach the end of the paginated
+result set or until additional resources are retrieved from the web service.
+
+Update the nextToken property
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Beyond fetching more results, the ``sendRequest()`` method is responsible for updating the ``$this->nextToken``
+property of the iterator. Setting this property to anything other than null tells the iterator that issuing a
+subsequent request using the nextToken value will probably return more results. You must continually update this
+value in your ``sendRequest()`` method as each response is received from the web service.
+
+Example iterator
+----------------
+
+Let's say you want to implement a resource iterator for the ``get_users`` command of your web service. The
+``get_users`` command receives a response that contains a list of users, and if there are more pages of results to
+retrieve, returns a value called ``next_user``. This return value is known as the **next token** and should be used to
+issue subsequent requests.
+
+Assume the response to a ``get_users`` command returns JSON data that looks like this:
+
+.. code-block:: javascript
+
+    {
+        "users": [
+            { "name": "Craig Johnson", "age": 10 },
+            { "name": "Tom Barker", "age": 20 },
+            { "name": "Bob Mitchell", "age": 74 }
+        ],
+        "next_user": "Michael Dowling"
+    }
+
+Assume that because there is a ``next_user`` value, there will be more users if a subsequent request is issued. If the
+``next_user`` value is missing or null, then we know there are no more results to fetch. Let's implement a resource
+iterator for this command.
+
+.. code-block:: php
+
+    namespace MyService\Model;
+
+    use Guzzle\Service\Resource\ResourceIterator;
+
+    /**
+     * Iterate over a get_users command
+     */
+    class GetUsersIterator extends ResourceIterator
+    {
+        protected function sendRequest()
+        {
+            // If a next token is set, then add it to the command
+            if ($this->nextToken) {
+                $this->command->set('next_user', $this->nextToken);
+            }
+
+            // Execute the command and parse the result
+            $result = $this->command->execute();
+
+            // Parse the next token
+            $this->nextToken = isset($result['next_user']) ? $result['next_user'] : false;
+
+            return $result['users'];
+        }
+    }
+
+As you can see, it's pretty simple to implement an iterator. There are a few things that you should notice from this
+example:
+
+1. You do not need to create a new command in the ``sendRequest()`` method. A new command object is cloned from the
+   original command passed into the constructor of the iterator before the ``sendRequest()`` method is called.
+   Remember that the resource iterator expects a command that has not been executed.
+2. When the ``sendRequest()`` method is first called, you will not have a ``$this->nextToken`` value, so always check
+   before setting it on a command. Notice that the next token is being updated each time a request is sent.
+3. After fetching more resources from the service, always return an array of resources.

+=================
+HTTP Cache plugin
+=================
+
+Guzzle can leverage HTTP's caching specifications using the ``Guzzle\Plugin\Cache\CachePlugin``. The CachePlugin
+provides a private transparent proxy cache that caches HTTP responses. The caching logic, based on
+`RFC 2616 <http://www.w3.org/Protocols/rfc2616/rfc2616-sec13.html>`_, uses HTTP headers to control caching behavior,
+cache lifetime, and supports Vary, ETag, and Last-Modified based revalidation:
+
+.. code-block:: php
+
+    use Guzzle\Http\Client;
+    use Doctrine\Common\Cache\FilesystemCache;
+    use Guzzle\Cache\DoctrineCacheAdapter;
+    use Guzzle\Plugin\Cache\CachePlugin;
+    use Guzzle\Plugin\Cache\DefaultCacheStorage;
+
+    $client = new Client('http://www.test.com/');
+
+    $cachePlugin = new CachePlugin(array(
+        'storage' => new DefaultCacheStorage(
+            new DoctrineCacheAdapter(
+                new FilesystemCache('/path/to/cache/files')
+            )
+        )
+    ));
+
+    // Add the cache plugin to the client object
+    $client->addSubscriber($cachePlugin);
+    $client->get('http://www.wikipedia.org/')->send();
+
+    // The next request will revalidate against the origin server to see if it
+    // has been modified. If a 304 response is received the response will be
+    // served from cache
+    $client->get('http://www.wikipedia.org/')->send();
+
+The cache plugin intercepts GET and HEAD requests before they are actually transferred to the origin server. The cache
+plugin then generates a hash key based on the request method and URL, and checks to see if a response exists in the cache. If
+a response exists in the cache, the cache adapter then checks to make sure that the caching rules associated with the response
+satisfy the request, and ensures that response still fresh. If the response is acceptable for the request any required
+revalidation, then the cached response is served instead of contacting the origin server.
+
+Vary
+----
+
+Cache keys are derived from a request method and a request URL. Multiple responses can map to the same cache key and
+stored in Guzzle's underlying cache storage object. You should use the ``Vary`` HTTP header to tell the cache storage
+object that the cache response must have been cached for a request that matches the headers specified in the Vary header
+of the request. This allows you to have specific cache entries for the same request URL but variations in a request's
+headers determine which cache entry is served. Please see the http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.44
+for more information.
+
+Cache options
+-------------
+
+There are several options you can add to requests or clients to modify the behavior of the cache plugin.
+
+Override cache TTL
+~~~~~~~~~~~~~~~~~~
+
+You can override the number of seconds a cacheable response is stored in the cache by setting the
+``cache.override_ttl`` parameter on the params object of a request:
+
+.. code-block:: php
+
+    // If the response to the request is cacheable, then the response will be cached for 100 seconds
+    $request->getParams()->set('cache.override_ttl', 100);
+
+If a response doesn't specify any freshness policy, it will be kept in cache for 3600 seconds by default.
+
+Custom caching decision
+~~~~~~~~~~~~~~~~~~~~~~~
+
+If the service you are interacting with does not return caching headers or returns responses that are normally
+something that would not be cached, you can set a custom ``can_cache`` object on the constructor of the CachePlugin
+and provide a ``Guzzle\Plugin\Cache\CanCacheInterface`` object. You can use the
+``Guzzle\Plugin\Cache\CallbackCanCacheStrategy`` to easily make a caching decision based on an HTTP request and
+response.
+
+Revalidation options
+~~~~~~~~~~~~~~~~~~~~
+
+You can change the revalidation behavior of a request using the ``cache.revalidate`` parameter. Setting this
+parameter to ``never`` will ensure that a revalidation request is never sent, and the response is always served from
+the origin server. Setting this parameter to ``skip`` will never revalidate and uses the response stored in the cache.
+
+Normalizing requests for caching
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Use the ``cache.key_filter`` parameter if you wish to strip certain query string parameters from your
+request before creating a unique hash for the request. This parameter can be useful if your requests have query
+string values that cause each request URL to be unique (thus preventing a cache hit). The ``cache.key_filter``
+format is simply a comma separated list of query string values to remove from the URL when creating a cache key.
+For example, here we are saying that the ``a`` and ``q`` query string variables should be ignored when generating a
+cache key for the request:
+
+.. code-block:: php
+
+    $request->getParams()->set('cache.key_filter', 'a, q');
+
+Other options
+~~~~~~~~~~~~~
+
+There are many other options available to the CachePlugin that can meet almost any caching requirement, including
+custom revalidation implementations, custom cache key generators, custom caching decision strategies, and custom
+cache storage objects. Take a look the constructor of ``Guzzle\Plugin\Cache\CachePlugin`` for more information.
+
+Setting Client-wide cache settings
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+You can specify cache settings for every request created by a client by adding cache settings to the configuration
+options of a client.
+
+.. code-block:: php
+
+    $client = new Guzzle\Http\Client('http://www.test.com', array(
+        'request.params' => array(
+            'cache.override_ttl' => 3600,
+            'params.cache.revalidate' => 'never'
+        )
+    ));
+
+    echo $client->get('/')->getParams()->get('cache.override_ttl');
+    // >>> 3600
+
+    echo $client->get('/')->getParams()->get('cache.revalidate');
+    // >>> never
+
+Cache revalidation
+------------------
+
+If the cache plugin determines that a response to a GET request needs revalidation, a conditional GET is transferred
+to the origin server. If the origin server returns a 304 response, then a response containing the merged headers of
+the cached response with the new response and the entity body of the cached response is returned. Custom revalidation
+strategies can be injected into a CachePlugin if needed.
+
+Cache adapters
+--------------
+
+Guzzle doesn't try to reinvent the wheel when it comes to caching or logging. Plenty of other frameworks have
+excellent solutions in place that you are probably already using in your applications. Guzzle uses adapters for
+caching and logging. The cache plugin requires a cache adapter so that is can store responses in a cache. Guzzle
+currently supports cache adapters for `Doctrine 2.0 <http://www.doctrine-project.org/>`_ and the
+`Zend Framework <http://framework.zend.com>`_.
+
+Doctrine cache adapter

+    use Zend\Cache\Backend\TestBackend;

+================
+Creating plugins
+================
+
+.. highlight:: php
+
+Guzzle is extremely extensible because of the behavioral modifications that can be added to requests, clients, and
+commands using an event system. Before and after the majority of actions are taken in the library, an event is emitted
+with the name of the event and context surrounding the event. Observers can subscribe to a subject and modify the
+subject based on the events received. Guzzle's event system utilizes the Symfony2 EventDispatcher and is the backbone
+of its plugin architecture.
+
+Overview
+--------
+
+Plugins must implement the ``Symfony\Component\EventDispatcher\EventSubscriberInterface`` interface. The
+``EventSubscriberInterface`` requires that your class implements a static method, ``getSubscribedEvents()``, that
+returns an associative array mapping events to methods on the object. See the
+`Symfony2 documentation <http://symfony.com/doc/2.0/book/internals.html#the-event-dispatcher>`_ for more information.
+
+Plugins can be attached to any subject, or object in Guzzle that implements that
+``Guzzle\Common\HasDispatcherInterface``.
+
+Subscribing to a subject
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+You can subscribe an instantiated observer to an event by calling ``addSubscriber`` on a subject.
+
+.. code-block:: php
+
+    $testPlugin = new TestPlugin();
+    $client->addSubscriber($testPlugin);
+
+You can also subscribe to only specific events using a closure::
+
+    $client->getEventDispatcher()->addListener('request.create', function(Event $event) {
+        echo $event->getName();
+        echo $event['request'];
+    });
+
+``Guzzle\Common\Event`` objects are passed to notified functions. The Event object has a ``getName()`` method which
+return the name of the emitted event and may contain contextual information that can be accessed like an array.
+
+Knowing what events to listen to
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Any class that implements the ``Guzzle\Common\HasDispatcherInterface`` must implement a static method,
+``getAllEvents()``, that returns an array of the events that are emitted from the object.  You can browse the source
+to see each event, or you can call the static method directly in your code to get a list of available events.
+
+Event hooks
+-----------
+
+* :ref:`client-events`
+* :ref:`service-client-events`
+* :ref:`request-events`
+* ``Guzzle\Http\Curl\CurlMulti``:
+* :ref:`service-builder-events`
+
+Examples of the event system
+----------------------------
+
+Simple Echo plugin
+~~~~~~~~~~~~~~~~~~
+
+This simple plugin prints a string containing the request that is about to be sent by listening to the
+``request.before_send`` event::
+
+    use Symfony\Component\EventDispatcher\EventSubscriberInterface;
+
+    class EchoPlugin implements EventSubscriberInterface
+    {
+        public static function getSubscribedEvents()
+        {
+            return array('request.before_send' => 'onBeforeSend');
+        }
+
+        public function onBeforeSend(Guzzle\Common\Event $event)
+        {
+            echo 'About to send a request: ' . $event['request'] . "\n";
+        }
+    }
+
+    $client = new Guzzle\Service\Client('http://www.test.com/');
+
+    // Create the plugin and add it as an event subscriber
+    $plugin = new EchoPlugin();
+    $client->addSubscriber($plugin);
+
+    // Send a request and notice that the request is printed to the screen
+    $client->get('/')->send();
+
+Running the above code will print a string containing the HTTP request that is about to be sent.

+MD5 validator plugin
+====================

+Entity bodies can sometimes be modified over the wire due to a faulty TCP transport or misbehaving proxy. If an HTTP
+response contains a Content-MD5 header, then a MD5 hash of the entity body of a response can be compared against the
+Content-MD5 header of the response to determine if the response was delivered intact. The

+
+.. code-block:: php
+
+    use Guzzle\Http\Client;
+    use Guzzle\Plugin\Oauth\OauthPlugin;

+    ));
+    $client->addSubscriber($oauth);
+
+    $response = $client->get('statuses/public_timeline.json')->send();
+
+If you need to use a custom signing method, you can pass a ``signature_method`` configuration option in the
+constructor of the OAuth plugin. The ``signature_method`` option must be a callable variable that accepts a string to
+sign and signing key and returns a signed string.
+
+.. note::
+
+    You can omit the ``token`` and ``token_secret`` options to use two-legged OAuth.

+======================
+Plugin system overview
+======================
+
+The workflow of sending a request and parsing a response is driven by Guzzle's event system, which is powered by the
+`Symfony2 Event Dispatcher component <http://symfony.com/doc/current/components/event_dispatcher/introduction.html>`_.
+
+Any object in Guzzle that emits events will implement the ``Guzzle\Common\HasEventDispatcher`` interface. You can add
+event subscribers directly to these objects using the ``addSubscriber()`` method, or you can grab the
+``Symfony\Component\EventDispatcher\EventDispatcher`` object owned by the object using ``getEventDispatcher()`` and
+add a listener or event subscriber.
+
+Adding event subscribers to clients
+-----------------------------------
+
+Any event subscriber or event listener attached to the EventDispatcher of a ``Guzzle\Http\Client`` or
+``Guzzle\Service\Client`` object will automatically be attached to all request objects created by the client. This
+allows you to attach, for example, a HistoryPlugin to a client object, and from that point on, every request sent
+through that client will utilize the HistoryPlugin.
+
+.. code-block:: php
+
+    use Guzzle\Plugin\History\HistoryPlugin;
+    use Guzzle\Service\Client;
+
+    $client = new Client();
+
+    // Create a history plugin and attach it to the client
+    $history = new HistoryPlugin();
+    $client->addSubscriber($history);
+
+    // Create and send a request. This request will also utilize the HistoryPlugin
+    $client->get('http://httpbin.org')->send();
+
+    // Echo out the last sent request by the client
+    echo $history->getLastRequest();
+
+.. tip::
+
+    :doc:`Create event subscribers <creating-plugins>`, or *plugins*, to implement reusable logic that can be
+    shared across clients. Event subscribers are also easier to test than anonymous functions.
+
+Pre-Built plugins

+===========================
+Unit Testing Guzzle clients
+===========================
+
+Guzzle provides several tools that will enable you to easily unit test your web service clients.
+
+* PHPUnit integration
+* Mock responses
+* node.js web server for integration testing
+
+PHPUnit integration
+-------------------
+
+Guzzle is unit tested using `PHPUnit <http://www.phpunit.de/>`_.  Your web service client's unit tests should extend
+``Guzzle\Tests\GuzzleTestCase`` so that you can take advantage of some of the built in helpers.
+
+In order to unit test your client, a developer would need to copy phpunit.xml.dist to phpunit.xml and make any needed
+modifications.  As a best practice and security measure for you and your contributors, it is recommended to add an
+ignore statement to your SCM so that phpunit.xml is ignored.
+
+Bootstrapping
+~~~~~~~~~~~~~
+
+Your web service client should have a tests/ folder that contains a bootstrap.php file. The bootstrap.php file
+responsible for autoloading and configuring a ``Guzzle\Service\Builder\ServiceBuilder`` that is used throughout your
+unit tests for loading a configured client. You can add custom parameters to your phpunit.xml file that expects users
+to provide the path to their configuration data.
+
+.. code-block:: php
+
+    Guzzle\Tests\GuzzleTestCase::setServiceBuilder(Aws\Common\Aws::factory($_SERVER['CONFIG']));
+
+    Guzzle\Tests\GuzzleTestCase::setServiceBuilder(Guzzle\Service\Builder\ServiceBuilder::factory(array(
+        'test.unfuddle' => array(
+            'class' => 'Guzzle.Unfuddle.UnfuddleClient',
+            'params' => array(
+                'username' => 'test_user',
+                'password' => '****',
+                'subdomain' => 'test'
+            )
+        )
+    )));
+
+The above code registers a service builder that can be used throughout your unit tests.  You would then be able to
+retrieve an instantiated and configured Unfuddle client by calling ``$this->getServiceBuilder()->get('test.unfuddle)``.
+The above code assumes that ``$_SERVER['CONFIG']`` contains the path to a file that stores service description
+configuration.
+
+Unit testing remote APIs
+------------------------
+
+Mock responses
+~~~~~~~~~~~~~~
+
+One of the benefits of unit testing is the ability to quickly determine if there are errors in your code.  If your
+unit tests run slowly, then they become tedious and will likely be run less frequently.  Guzzle's philosophy on unit
+testing web service clients is that no network access should be required to run the unit tests.  This means that
+responses are served from mock responses or local servers.  By adhering to this principle, tests will run much faster
+and will not require an external resource to be available.  The problem with this approach is that your mock responses
+must first be gathered and then subsequently updated each time the remote API changes.
+
+Integration testing over the internet
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+You can perform integration testing with a web service over the internet by making calls directly to the service. If
+the web service you are requesting uses a complex signing algorithm or some other specific implementation, then you
+may want to include at least one actual network test that can be run specifically through the command line using
+`PHPUnit group annotations <http://www.phpunit.de/manual/current/en/appendixes.annotations.html#appendixes.annotations.group>`_.
+
+@group internet annotation
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+When creating tests that require an internet connection, it is recommended that you add ``@group internet`` annotations
+to your unit tests to specify which tests require network connectivity.
+
+You can then `run PHPUnit tests <http://www.phpunit.de/manual/current/en/textui.html>`_ that exclude the @internet
+group by running ``phpunit --exclude-group internet``.
+
+API credentials
+^^^^^^^^^^^^^^^
+
+If API  credentials are required to run your integration tests, you must add ``<php>`` parameters to your
+phpunit.xml.dist file and extract these parameters in your bootstrap.php file.
+
+.. code-block:: xml
+
+    <?xml version="1.0" encoding="UTF-8"?>
+    <phpunit bootstrap="./tests/bootstrap.php" colors="true">
+        <php>
+            <!-- Specify the path to a service configuration file -->
+            <server name="CONFIG" value="test_services.json" />
+            <!-- Or, specify each require parameter individually -->
+            <server name="API_USER" value="change_me" />
+            <server name="API_PASSWORD" value="****" />
+        </php>
+        <testsuites>
+            <testsuite name="guzzle-service">
+                <directory suffix="Test.php">./Tests</directory>
+            </testsuite>
+        </testsuites>
+    </phpunit>
+
+You can then extract the ``server`` variables in your bootstrap.php file by grabbing them from the ``$_SERVER``
+superglobal: ``$apiUser = $_SERVER['API_USER'];``
+
+Further reading
+^^^^^^^^^^^^^^^
+
+A good discussion on the topic of testing remote APIs can be found in Sebastian Bergmann's
+`Real-World Solutions for Developing High-Quality PHP Frameworks and Applications <http://www.amazon.com/dp/0470872497>`_.
+
+Queueing Mock responses
+-----------------------
+
+Mock responses can be used to test if requests are being generated correctly and responses and handled correctly by
+your client.  Mock responses can be queued up for a client using the ``$this->setMockResponse($client, $path)`` method
+of your test class.  Pass the client you are adding mock responses to and a single path or array of paths to mock
+response files relative to the ``/tests/mock/ folder``.  This will queue one or more mock responses for your client by
+creating a simple observer on the client.  Mock response files must contain a full HTTP response message:
+
+.. code-block:: none
+
+    HTTP/1.1 200 OK
+    Date: Wed, 25 Nov 2009 12:00:00 GMT
+    Connection: close
+    Server: AmazonS3
+    Content-Type: application/xml
+
+    <?xml version="1.0" encoding="UTF-8"?>
+    <LocationConstraint xmlns="http://s3.amazonaws.com/doc/2006-03-01/">EU</LocationConstraint>
+
+After queuing mock responses for a client, you can get an array of the requests that were sent by the client that
+were issued a mock response by calling ``$this->getMockedRequests()``.
+
+You can also use the ``Guzzle\Plugin\Mock\MockPlugin`` object directly with your clients.
+
+.. code-block:: php
+
+    $plugin = new Guzzle\Plugin\Mock\MockPlugin();
+    $plugin->addResponse(new Guzzle\Http\Message\Response(200));
+    $client = new Guzzle\Http\Client();
+    $client->addSubscriber($plugin);
+
+    // The following request will get the mock response from the plugin in FIFO order
+    $request = $client->get('http://www.test.com/');
+    $request->send();
+
+    // The MockPlugin maintains a list of requests that were mocked
+    $this->assertContainsOnly($request, $plugin->getReceivedRequests());
+
+node.js web server for integration testing
+------------------------------------------
+
+Using mock responses is usually enough when testing a web service client.  If your client needs to add custom cURL
+options to requests, then you should use the node.js test web server to ensure that your HTTP request message is
+being created correctly.
+
+Guzzle is based around PHP's libcurl bindings.  cURL sometimes modifies an HTTP request message based on
+``CURLOPT_*`` options.  Headers that are added to your request by cURL will not be accounted for if you inject mock
+responses into your tests.  Additionally, some request entity bodies cannot be loaded by the client before transmitting
+it to the sever (for example, when using a client as a sort of proxy and streaming content from a remote server). You
+might also need to inspect the entity body of a ``multipart/form-data`` POST request.
+
+.. note::
+
+    You can skip all of the tests that require the node.js test web server by excluding the ``server`` group:
+    ``phpunit --exclude-group server``
+
+Using the test server
+~~~~~~~~~~~~~~~~~~~~~
+
+The node.js test server receives requests and returns queued responses.  The test server exposes a simple API that is
+used to enqueue responses and inspect the requests that it has received.
+
+Retrieve the server object by calling ``$this->getServer()``.  If the node.js server is not running, it will be
+started as a forked process and an object that interfaces with the server will be returned.  (note: stopping the
+server is handled internally by Guzzle.)
+
+You can queue an HTTP response or an array of responses by calling ``$this->getServer()->enqueue()``:
+
+.. code-block:: php
+
+    $this->getServer()->enqueue("HTTP/1.1 200 OK\r\nContent-Length: 0\r\n\r\n");
+
+The above code queues a single 200 response with an empty body.  Responses are queued using a FIFO order; this
+response will be returned by the server when it receives the first request and then removed from the queue. If a
+request is received by a server with no queued responses, an exception will be thrown in your unit test.
+
+You can inspect the requests that the server has retrieved by calling ``$this->getServer()->getReceivedRequests()``.
+This method accepts an optional ``$hydrate`` parameter that specifies if you are retrieving an array of string HTTP
+requests or an array of ``Guzzle\Http\RequestInterface`` subclassed objects.  "Hydrating" the requests will allow
+greater flexibility in your unit tests so that you can  easily assert the state of the various parts of a request.
+
+You will need to modify the base_url of your web service client in order to use it against the test server.
+
+.. code-block:: php
+
+    $client = $this->getServiceBuilder()->get('my_client');
+    $client->setBaseUrl($this->getServer()->getUrl());
+
+After running the above code, all calls made from the ``$client`` object will be sent to the test web server.

+Guzzle service descriptions
+===========================
+
+Guzzle allows you to serialize HTTP requests and parse HTTP responses using a DSL called a service descriptions.
+Service descriptions define web service APIs by documenting each operation, the operation's parameters, validation
+options for each parameter, an operation's response, how the response is parsed, and any errors that can be raised for
+an operation. Writing a service description for a web service allows you to more quickly consume a web service than
+writing concrete commands for each web service operation.
+
+Guzzle service descriptions can be representing using a PHP array or JSON document. Guzzle's service descriptions are
+heavily inspired by `Swagger <http://swagger.wordnik.com/>`_.
+
+Service description schema
+==========================
+
+A Guzzle Service description must match the following JSON schema document. This document can also serve as a guide when
+implementing a Guzzle service description.

+Operations
+----------
+
+Operations are the actions that can be taken on a service. Each operation is given a unique name and has a distinct
+endpoint and HTTP method. If an API has a ``DELETE /users/:id`` operation, a satisfactory operation name might be
+``DeleteUser`` with a parameter of ``id`` that is inserted into the URI.

+
+additionalParameters
+~~~~~~~~~~~~~~~~~~~~
+
+When a webservice offers a large number of parameters that all are set in the same location (for example the query
+string or a JSON document), defining each parameter individually can require a lot of time and repetition. Furthermore,
+some web services allow for completely arbitrary parameters to be supplied for an operation. The
+``additionalParameters`` attribute can be used to solve both of these issues.
+
+As an example, we can define a Twitter API operation quite easily using ``additionalParameters``. The
+GetMentions operation accepts a large number of query string parameters. Defining each of these parameters
+is ideal because it provide much more introspection for the client and opens the possibility to use the description with
+other tools (e.g. a documentation generator). However, you can very quickly provide a "catch-all" serialization rule
+that will place any custom parameters supplied to an operation the generated request's query string parameters.

+                    }
+                }
+            }
+        }
+
+responseClass
+~~~~~~~~~~~~~
+
+The ``responseClass`` attribute is used to define the return value of an operation (what is returned by calling the
+``getResult()`` method of a command object). The value set in the responseClass attribute can be one of "primitive"
+(meaning the result with be primitive type like a string), a class name meaning the result will be an instance of a
+specific user-land class, or a model name meaning the result will be a ``Guzzle\Service\Resource\Model`` object that
+uses a :ref:`model schema <model-schema>` to define how the HTTP response is parsed.
+
+.. note::
+
+    Using a class name with a ``responseClass`` will only work if it is supported by the ``class`` that is instantiated
+    for the operation. Keep this in mind when specifying a custom ``class`` attribute that points to a custom
+    ``Guzzle\Service\Command\CommandInterface`` class. The default ``class``,
+    ``Guzzle\Service\Command\OperationCommand``, does support setting custom ``class`` attributes.
+
+You can specify the name of a class to return a more customized result from the operation (for example, a domain model
+object). When using the name of a PHP class, the class must implement ``Guzzle\Service\Command\ResponseClassInterface``.
+Here's a very simple example of implementing a custom responseClass object.
+
+.. code-block:: json
+
+    {
+        "operations": {
+            "test": {
+                "responseClass": "MyApplication\\User"
+            }
+        }
+    }
+
+.. code-block:: php
+
+    namespace MyApplication;
+
+    use Guzzle\Service\Command\ResponseClassInterface;
+    use Guzzle\Service\Command\OperationCommand;
+
+    class User implements ResponseClassInterface
+    {
+        protected $name;
+
+        public static function fromCommand(OperationCommand $command)
+        {
+            $response = $command->getResponse();
+            $xml = $response->xml();
+
+            return new self((string) $xml->name);
+        }
+
+        public function __construct($name)
+        {
+            $this->name = $name;
+        }
+    }
+
+errorResponses
+~~~~~~~~~~~~~~
+
+``errorResponses`` is an array containing objects that define the errors that could occur while executing the
+operation. Each item of the array is an object that can contain a 'code' (HTTP response status code of the error),
+'reason' (reason phrase or description of the error), and 'class' (an exception class that will be raised when this
+error is encountered).
+
+ErrorResponsePlugin
+^^^^^^^^^^^^^^^^^^^
+
+Error responses are by default only used for documentation. If you don't need very complex exception logic for your web
+service errors, then you can use the ``Guzzle\Plugin\ErrorResponse\ErrorResponsePlugin`` to automatically throw defined
+exceptions when one of the ``errorResponse`` rules are matched. The error response plugin will listen for the
+``request.complete`` event of a request created by a command object. Every response (including a successful response) is
+checked against the list of error responses for an exact match using the following order of checks:
+
+1. Does the errorResponse have a defined ``class``?
+2. Is the errorResponse ``code`` equal to the status code of the response?
+3. Is the errorResponse ``reason`` equal to the reason phrase of the response?
+4. Throw the exception stored in the ``class`` attribute of the errorResponse.
+
+The ``class`` attribute must point to a class that implements
+``Guzzle\Plugin\ErrorResponse\ErrorResponseExceptionInterface``. This interface requires that an error response class
+implements ``public static function fromCommand(CommandInterface $command, Response $response)``. This method must
+return an object that extends from ``\Exception``. After an exception is returned, it is thrown by the plugin.
+
+.. _parameter-schema:
+
+Parameter schema
+----------------
+
+Parameters in both operations and models are represented using the
+`JSON schema <http://tools.ietf.org/id/draft-zyp-json-schema-04.html>`_ syntax.
+
+.. csv-table::
+   :header: "Property Name", "Value", "Description"
+   :widths: 20, 15, 65
+
+    "name", "string", "Unique name of the parameter"
+    "type", "string|array", "Type of variable (string, number, integer, boolean, object, array, numeric, null, any). Types are using for validation and determining the structure of a parameter. You can use a union type by providing an array of simple types. If one of the union types matches the provided value, then the value is valid."
+    "instanceOf", "string", "When the type is an object, you can specify the class that the object must implement"
+    "required", "boolean", "Whether or not the parameter is required"
+    "default", "mixed", "Default value to use if no value is supplied"
+    "static", "boolean", "Set to true to specify that the parameter value cannot be changed from the default setting"
+    "description", "string", "Documentation of the parameter"
+    "location", "string", "The location of a request used to apply a parameter. Custom locations can be registered with a command, but the defaults are uri, query, statusCode, reasonPhrase, header, body, json, xml, postField, postFile, responseBody"
+    "sentAs", "string", "Specifies how the data being modeled is sent over the wire. For example, you may wish to include certain headers in a response model that have a normalized casing of FooBar, but the actual header is x-foo-bar. In this case, sentAs would be set to x-foo-bar."
+    "filters", "array", "Array of functions to to run a parameter value through."
+
+filters
+~~~~~~~
+
+Each value in the array must be a string containing the full class path to a static method or an array of complex
+filter information. You can specify static methods of classes using the full namespace class name followed by
+"::" (e.g. ``FooBar::baz()``). Some filters require arguments in order to properly filter a value. For complex filters,
+use an object containing a ``method`` attribute pointing to a function, and an ``args`` attribute containing an
+array of positional arguments to pass to the function. Arguments can contain keywords that are replaced when filtering
+a value: ``@value`` is replaced with the value being filtered, and ``@api`` is replaced with the actual Parameter
+object.
+
+.. code-block:: json
+
+    {
+        "filters": [
+            "strtolower",
+            {
+                "method": "MyClass::convertString",
+                "args": [ "test", "@value", "@api" ]
+            }
+        ]
+    }
+
+The above example will filter a parameter using ``strtolower``. It will then call the ``convertString`` static method
+of ``MyClass``, passing in "test", the actual value of the parameter, and a ``Guzzle\Service\Description\Parameter``
+object.
+
+Operation parameter location attributes
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The location field of top-level parameters control how a parameter is serialized when generating a request.
+
+uri location
+^^^^^^^^^^^^
+
+Parameters are injected into the ``uri`` attribute of the operation using
+`URI-template expansion <http://tools.ietf.org/html/rfc6570>`_.
+
+.. code-block:: json
+
+    {
+        "operations": {
+            "uriTest": {
+                "uri": "/test/{testValue}",
+                "parameters": {
+                    "testValue": {
+                        "location": "uri"
+                    }
+                }
+            }
+        }
+    }
+
+query location
+^^^^^^^^^^^^^^
+
+Parameters are injected into the query string of a request. Query values can be nested, which would result in a PHP
+style nested query string. The name of a parameter is the default name of the query string parameter added to the
+request. You can override this behavior by specifying the ``sentAs`` attribute on the parameter.
+
+.. code-block:: json
+
+    {
+        "operations": {
+            "queryTest": {
+                "parameters": {
+                    "testValue": {
+                        "location": "query",
+                        "sentAs": "test_value"
+                    }
+                }
+            }
+        }
+    }
+
+header location
+^^^^^^^^^^^^^^^
+
+Parameters are injected as headers on an HTTP request. The name of the parameter is used as the name of the header by
+default. You can change the name of the header created by the parameter using the ``sentAs`` attribute.
+
+Headers that are of type ``object`` will be added as multiple headers to a request using the key of the input array as
+the header key. Setting a ``sentAs`` attribute along with a type ``object`` will use the value of ``sentAs`` as a
+prefix for each header key.
+
+body location
+^^^^^^^^^^^^^
+
+Parameters are injected as the body of a request. The input of these parameters may be anything that can be cast to a
+string or a ``Guzzle\Http\EntityBodyInterface`` object.
+
+postField location
+^^^^^^^^^^^^^^^^^^
+
+Parameters are inserted as POST fields in a request. Nested values may be supplied and will be represented using
+PHP style nested query strings. The POST field name is the same as the parameter name by default. You can use the
+``sentAs`` parameter to override the POST field name.
+
+postFile location
+^^^^^^^^^^^^^^^^^
+
+Parameters are added as POST files. A postFile value may be a string pointing to a local filename or a
+``Guzzle\Http\Message\PostFileInterface`` object. The name of the POST file will be the name of the parameter by
+default. You can use a custom POST file name by using the ``sentAs`` attribute.
+
+Supports "string" and "array" types.
+
+json location
+^^^^^^^^^^^^^
+
+Parameters are added to the body of a request as top level keys of a JSON document. Nested values may be specified,
+with any number of nested ``Guzzle\Common\ToArrayInterface`` objects. When JSON parameters are specified, the
+``Content-Type`` of the request will change to ``application/json`` if a ``Content-Type`` has not already been specified
+on the request.
+
+xml location
+^^^^^^^^^^^^
+
+Parameters are added to the body of a request as top level nodes of an XML document. Nested values may be specified,
+with any number of nested ``Guzzle\Common\ToArrayInterface`` objects. When XML parameters are specified, the
+``Content-Type`` of the request will change to ``application/xml`` if a ``Content-Type`` has not already been specified
+on the request.
+
+responseBody location
+^^^^^^^^^^^^^^^^^^^^^
+
+Specifies the EntityBody of a response. This can be used to download the response body to a file or a custom Guzzle
+EntityBody object.
+
+No location
+^^^^^^^^^^^
+
+If a parameter has no location attribute, then the parameter is simply used as a data value.
+
+Other locations
+^^^^^^^^^^^^^^^
+
+Custom locations can be registered as new locations or override default locations if needed.
+
+.. _model-schema:
+
+Model Schema
+------------
+
+Models are used in service descriptions to provide generic JSON schema definitions that can be extended from or used in
+``$ref`` attributes. Models can also be referenced in a ``responseClass`` attribute to provide valuable output to an
+operation. Models are JSON schema documents and use the exact syntax and attributes used in parameters.
+
+Response Models
+~~~~~~~~~~~~~~~
+
+Response models describe how a response is parsed into a ``Guzzle\Service\Resource\Model`` object. Response models are
+always modeled as JSON schema objects. When an HTTP response is parsed using a response model, the rules specified on
+each property of a response model will translate 1:1 as keys in a PHP associative array. When a ``sentAs`` attribute is
+found in response model parameters, the value retrieved from the HTTP response is retrieved using the ``sentAs``
+parameter but stored in the response model using the name of the parameter.
+
+The location field of top-level parameters in a response model tell response parsers how data is retrieved from a
+response.
+
+statusCode location
+^^^^^^^^^^^^^^^^^^^
+
+Retrieves the status code of the response.
+
+reasonPhrase location
+^^^^^^^^^^^^^^^^^^^^^
+
+Retrieves the reason phrase of the response.
+
+header location
+^^^^^^^^^^^^^^^
+
+Retrieves a header from the HTTP response.
+
+body location
+^^^^^^^^^^^^^
+
+Retrieves the body of an HTTP response.
+
+json location
+^^^^^^^^^^^^^
+
+Retrieves a top-level parameter from a JSON document contained in an HTTP response.
+
+You can use ``additionalProperties`` if the JSON document is wrapped in an outer array. This allows you to parse the
+contents of each item in the array using the parsing rules defined in the ``additionalProperties`` schema.
+
+xml location
+^^^^^^^^^^^^
+
+Retrieves a top-level node value from an XML document contained in an HTTP response.
+
+Other locations
+^^^^^^^^^^^^^^^
+
+Custom locations can be registered as new locations or override default locations if needed.
+
+Example service description
+---------------------------
+
+Let's say you're interacting with a web service called 'Foo' that allows for the following routes and methods::
+
+    GET/POST   /users
+    GET/DELETE /users/:id

+            }
+        }
+
+If you attach this service description to a client, you would completely configure the client to interact with the
+Foo web service and provide valuable response models for each operation.
+
+.. code-block:: php
+
+    use Guzzle\Service\Description\ServiceDescription;
+
+    $description = ServiceDescription::factory('/path/to/client.json');

+
+    $command = $client->getCommand('DeleteUser', array('id' => 123));
+    $responseModel = $client->execute($command);
+    echo $responseModel['status'];
+
+.. note::
+
+    You can add the service description to your client's factory method or constructor.

+=======================
+Using a service builder
+=======================
+
+The best way to instantiate Guzzle web service clients is to let Guzzle handle building the clients for you using a
+ServiceBuilder. A ServiceBuilder is responsible for creating concrete client objects based on configuration settings
+and helps to manage credentials for different environments.
+
+You don't have to use a service builder, but they help to decouple your application from concrete classes and help to
+share configuration data across multiple clients. Consider the following example. Here we are creating two clients that
+require the same API public key and secret key. The clients are created using their ``factory()`` methods.
+
+.. code-block:: php
+
+    use MyService\FooClient;
+    use MyService\BarClient;
+
+    $foo = FooClient::factory(array(
+        'key'    => 'abc',
+        'secret' => '123',
+        'custom' => 'and above all'
+    ));
+
+    $bar = BarClient::factory(array(
+        'key'    => 'abc',
+        'secret' => '123',
+        'custom' => 'listen to me'
+    ));
+
+The redundant specification of the API keys can be removed using a service builder.
+
+.. code-block:: php
+
+    use Guzzle\Service\Builder\ServiceBuilder;
+
+    $builder = ServiceBuilder::factory(array(
+        'services' => array(
+            'abstract_client' => array(
+                'params' => array(
+                    'key'    => 'abc',
+                    'secret' => '123'
+                )
+            ),
+            'foo' => array(
+                'extends' => 'abstract_client',
+                'class'   => 'MyService\FooClient',
+                'params'  => array(
+                    'custom' => 'and above all'
+                )
+            ),
+            'bar' => array(
+                'extends' => 'abstract_client',
+                'class'   => 'MyService\FooClient',
+                'params'  => array(
+                    'custom' => 'listen to me'
+                )
+            )
+        )
+    ));
+
+    $foo = $builder->get('foo');
+    $bar = $builder->get('bar');
+
+You can make managing your API keys even easier by saving the service builder configuration in a JSON format in a
+.json file.
+
+Creating a service builder
+--------------------------
+
+A ServiceBuilder can source information from an array, an PHP include file that returns an array, or a JSON file.
+
+.. code-block:: php
+
+    use Guzzle\Service\Builder\ServiceBuilder;
+
+    // Source service definitions from a JSON file
+    $builder = ServiceBuilder::factory('services.json');
+
+Sourcing data from an array
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Data can be source from a PHP array. The array must contain an associative ``services`` array that maps the name of a
+client to the configuration information used by the service builder to create the client. Clients are given names
+which are used to identify how a client is retrieved from a service builder. This can be useful for using multiple
+accounts for the same service or creating development clients vs. production clients.
+
+.. code-block:: php
+
+    $services = array(
+        'includes' => array(
+            '/path/to/other/services.json',
+            '/path/to/other/php_services.php'
+        ),
+        'services' => array(
+            'abstract.foo' => array(
+                'params' => array(
+                    'username' => 'foo',
+                    'password' => 'bar'
+                )
+            ),
+            'bar' => array(
+                'extends' => 'abstract.foo',
+                'class'   => 'MyClientClass',
+                'params'  => array(
+                    'other' => 'abc'
+                )
+            )
+        )
+    );
+
+A service builder configuration array contains two top-level array keys:
+
++------------+---------------------------------------------------------------------------------------------------------+
+| Key        | Description                                                                                             |
++============+=========================================================================================================+
+| includes   | Array of paths to JSON or PHP include files to include in the configuration.                            |
++------------+---------------------------------------------------------------------------------------------------------+
+| services   | Associative array of defined services that can be created by the service builder. Each service can      |
+|            | contain the following keys:                                                                             |
+|            |                                                                                                         |
+|            | +------------+----------------------------------------------------------------------------------------+ |
+|            | | Key        | Description                                                                            | |
+|            | +============+========================================================================================+ |
+|            | | class      | The concrete class to instantiate that implements the                                  | |
+|            | |            | ``Guzzle\Common\FromConfigInterface``.                                                 | |
+|            | +------------+----------------------------------------------------------------------------------------+ |
+|            | | extends    | The name of a previously defined service to extend from                                | |
+|            | +------------+----------------------------------------------------------------------------------------+ |
+|            | | params     | Associative array of parameters to pass to the factory method of the service it is     | |
+|            | |            | instantiated                                                                           | |
+|            | +------------+----------------------------------------------------------------------------------------+ |
+|            | | alias      | An alias that can be used in addition to the array key for retrieving a client from    | |
+|            | |            | the service builder.                                                                   | |
+|            | +------------+----------------------------------------------------------------------------------------+ |
++------------+---------------------------------------------------------------------------------------------------------+
+
+The first client defined, ``abstract.foo``, is used as a placeholder of shared configuration values. Any service
+extending abstract.foo will inherit its params. As an example, this can be useful when clients share the same username
+and password.
+
+The next client, ``bar``, extends from ``abstract.foo`` using the ``extends`` attribute referencing the client from
+which to extend. Additional parameters can be merged into the original service definition when extending a parent
+service.
+
+.. important::
+
+    Each client that you intend to instantiate must specify a ``class`` attribute that references the full class name
+    of the client being created. The class referenced in the ``class`` parameter must implement a static ``factory()``
+    method that accepts an array or ``Guzzle\Common\Collection`` object and returns an instantiated object.
+
+Sourcing from a PHP include
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+You can create service builder configurations using a PHP include file. This can be useful if you wish to take
+advantage of an opcode cache like APC to speed up the process of loading and processing the configuration. The PHP
+include file is the same format as an array, but you simply create a PHP script that returns an array and save the
+file with the .php file extension.
+
+.. code-block:: php
+
+    <?php return array('services' => '...');
+    // Saved as config.php
+
+This configuration file can then be used with a service builder.
+
+.. code-block:: php
+
+    $builder = ServiceBuilder::factory('/path/to/config.php');
+
+Sourcing from a JSON document
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+You can use JSON documents to serialize your service descriptions. The JSON format uses the exact same structure as
+the PHP array syntax, but it's just serialized using JSON.
+
+.. code-block:: javascript
+
+    {
+        "includes": ["/path/to/other/services.json", "/path/to/other/php_services.php"],
+        "services": {
+            "abstract.foo": {
+                "params": {
+                    "username": "foo",
+                    "password": "bar"
+                }
+            },
+            "bar": {
+                "extends": "abstract.foo",
+                "class": "MyClientClass",
+                "params": {
+                    "other": "abc"
+                }
+            }
+        }
+    }
+
+Referencing other clients in parameters
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If one of your clients depends on another client as one of its parameters, you can reference that client by name by
+enclosing the client's reference key in ``{}``.
+
+.. code-block:: javascript
+
+    {
+        "services": {
+            "token": {
+                "class": "My\Token\TokenFactory",
+                "params": {
+                    "access_key": "xyz"
+                }
+            },
+            "client": {
+                "class": "My\Client",
+                "params": {
+                    "token_client": "{token}",
+                    "version": "1.0"
+                }
+            }
+        }
+    }
+
+When ``client`` is constructed by the service builder, the service builder will first create the ``token`` service
+and then inject the token service into ``client``'s factory method in the ``token_client`` parameter.
+
+Retrieving clients from a service builder
+-----------------------------------------
+
+Clients are referenced using a customizable name you provide in your service definition. The ServiceBuilder is a sort
+of multiton object-- it will only instantiate a client once and return that client for subsequent retrievals. Clients
+are retrieved by name (the array key used in the configuration) or by the ``alias`` setting of a service.
+
+Here's an example of retrieving a client from your ServiceBuilder:
+
+.. code-block:: php
+
+    $client = $builder->get('foo');
+
+    // You can also use the ServiceBuilder object as an array
+    $client = $builder['foo'];
+
+Creating throwaway clients
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+You can get a "throwaway" client (a client that is not persisted by the ServiceBuilder) by passing ``true`` in the
+second argument of ``ServiceBuilder::get()``. This allows you to create a client that will not be returned by other
+parts of your code that use the service builder. Instead of passing ``true``, you can pass an array of configuration
+settings that will override the configuration settings specified in the service builder.
+
+.. code-block:: php
+
+    // Get a throwaway client and overwrite the "custom" setting of the client
+    $foo = $builder->get('foo', array(
+        'custom' => 'in this world there are rules'
+    ));
+
+Getting raw configuration settings
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+You can get the raw configuration settings provided to the service builder for a specific service using the
+``getData($name)`` method of a service builder. This method will null if the service was not found in the service
+builder or an array of configuration settings if the service was found.
+
+.. code-block:: php
+
+    $data = $builder->getData('foo');
+    echo $data['key'] . "\n";
+    echo $data['secret'] . "\n";
+    echo $data['custom'] . "\n";
+
+Adding a plugin to all clients
+------------------------------
+
+You can add a plugin to all clients created by a service builder using the ``addGlobalPlugin($plugin)`` method of a
+service builder and passing a ``Symfony\Component\EventDispatcher\EventSubscriberInterface`` object. The service builder
+will then attach each global plugin to every client as it is created. This allows you to, for example, add a LogPlugin
+to every request created by a service builder for easy debugging.
+
+.. code-block:: php
+
+    use Guzzle\Plugin\Log\LogPlugin;
+
+    // Add a debug log plugin to every client as it is created
+    $builder->addGlobalPlugin(LogPlugin::getDebugPlugin());
+
+    $foo = $builder->get('foo');
+    $foo->get('/')->send();
+    // Should output all of the data sent over the wire
+
+.. _service-builder-events:
+
+Events emitted from a service builder
+-------------------------------------
+
+A ``Guzzle\Service\Builder\ServiceBuilder`` object emits the following events:
+
++-------------------------------+--------------------------------------------+-----------------------------------------+
+| Event name                    | Description                                | Event data                              |
++===============================+============================================+=========================================+
+| service_builder.create_client | Called when a client is created            | * client: The created client object     |
++-------------------------------+--------------------------------------------+-----------------------------------------+
+
+.. code-block:: php
+
+    use Guzzle\Common\Event;
+    use Guzzle\Service\Builder\ServiceBuilder;
+
+    $builder = ServiceBuilder::factory('/path/to/config.json');
+
+    // Add an event listener to print out each client client as it is created
+    $builder->getEventDispatcher()->addListener('service_builder.create_client', function (Event $e) {
+        echo 'Client created: ' . get_class($e['client']) . "\n";
+    });
+
+    $foo = $builder->get('foo');
+    // Should output the class used for the "foo" client

+The web service client
+======================
+
+The ``Guzzle\Service`` namespace contains various abstractions that help to make it easier to interact with a web
+service API, including commands, service descriptions, and resource iterators.
+
+In this chapter, we'll build a simple `Twitter API client <https://dev.twitter.com/docs/api/1.1>`_.
+
+Creating a client
+=================
+
+A class that extends from ``Guzzle\Service\Client`` or implements ``Guzzle\Service\ClientInterface`` must implement a

+
+Factory method

+
+You can use the ``factory()`` method of a client directly if you do not need a service builder.

+    $twitter = TwitterClient::factory(array(
+        'consumer_key'    => '****',
+        'consumer_secret' => '****',
+        'token'           => '****',
+        'token_secret'    => '****'
+    ));

+
+    1. Visit https://dev.twitter.com/apps
+    2. Click on an application that you've created
+    3. Click on the "OAuth tool" tab
+    4. Copy all of the settings under "OAuth Settings"
+
+Implementing a factory method
+-----------------------------
+
+Creating a client and its factory method is pretty simple. You just need to implement ``Guzzle\Service\ClientInterface``
+or extend from ``Guzzle\Service\Client``.
+
+.. code-block:: php
+
+    namespace mtdowling;
+
+    use Guzzle\Common\Collection;
+    use Guzzle\Plugin\Oauth\OauthPlugin;
+    use Guzzle\Service\Client;
+    use Guzzle\Service\Description\ServiceDescription;
+
+    /**
+     * A simple Twitter API client
+     */
+    class TwitterClient extends Client
+    {
+        public static function factory($config = array())
+        {
+            // Provide a hash of default client configuration options
+            $default = array('base_url' => 'https://api.twitter.com/1.1');
+
+            // The following values are required when creating the client
+            $required = array(
+                'base_url',
+                'consumer_key',
+                'consumer_secret',
+                'token',
+                'token_secret'
+            );
+
+            // Merge in default settings and validate the config
+            $config = Collection::fromConfig($config, $default, $required);
+
+            // Create a new Twitter client
+            $client = new self($config->get('base_url'), $config);
+
+            // Ensure that the OauthPlugin is attached to the client
+            $client->addSubscriber(new OauthPlugin($config->toArray()));
+
+            return $client;
+        }
+    }
+
+Service Builder
+---------------
+
+A service builder is used to easily create web service clients, provides a simple configuration driven approach to
+creating clients, and allows you to share configuration settings across multiple clients. You can find out more about
+Guzzle's service builder in :doc:`using-the-service-builder`.
+
+.. code-block:: php
+
+    use Guzzle\Service\Builder\ServiceBuilder;
+
+    // Create a service builder and provide client configuration data
+    $builder = ServiceBuilder::factory('/path/to/client_config.json');
+
+    // Get the client from the service builder by name
+    $twitter = $builder->get('twitter');
+
+The above example assumes you have JSON data similar to the following stored in "/path/to/client_config.json":
+
+.. code-block:: json
+
+    {
+        "services": {
+            "twitter": {
+                "class": "mtdowling\\TwitterClient",
+                "params": {
+                    "consumer_key": "****",
+                    "consumer_secret": "****",
+                    "token": "****",
+                    "token_secret": "****"
+                }
+            }
+        }
+    }
+
+.. note::
+
+    A service builder becomes much more valuable when using multiple web service clients in a single application or
+    if you need to utilize the same client with varying configuration settings (e.g. multiple accounts).
+
+Commands
+========
+
+Commands are a concept in Guzzle that helps to hide the underlying implementation of an API by providing an easy to use
+parameter driven object for each action of an API. A command is responsible for accepting an array of configuration
+parameters, serializing an HTTP request, and parsing an HTTP response. Following the
+`command pattern <http://en.wikipedia.org/wiki/Command_pattern>`_, commands in Guzzle offer a greater level of
+flexibility when implementing and utilizing a web service client.
+
+Executing commands
+------------------
+
+You must explicitly execute a command after creating a command using the ``getCommand()`` method. A command has an
+``execute()`` method that may be called, or you can use the ``execute()`` method of a client object and pass in the
+command object. Calling either of these execute methods will return the result value of the command. The result value is
+the result of parsing the HTTP response with the ``process()`` method.
+
+.. code-block:: php
+
+    // Get a command from the client and pass an array of parameters
+    $command = $twitter->getCommand('getMentions', array(
+        'count' => 5
+    ));
+
+    // Other parameters can be set on the command after it is created
+    $command['trim_user'] = false;
+
+    // Execute the command using the command object.
+    // The result value contains an array of JSON data from the response
+    $result = $command->execute();
+
+    // You can retrieve the result of the command later too
+    $result = $command->getResult().
+
+Command object also contains methods that allow you to inspect the HTTP request and response that was utilized with
+the command.
+
+.. code-block:: php
+
+    $request = $command->getRequest();
+    $response = $command->getResponse();
+
+.. note::
+
+    The format and notation used to retrieve commands from a client can be customized by injecting a custom command
+    factory, ``Guzzle\Service\Command\Factory\FactoryInterface``, on the client using ``$client->setCommandFactory()``.
+
+Executing with magic methods
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+When using method missing magic methods with a command, the command will be executed right away and the result of the
+command is returned.
+
+.. code-block:: php
+
+    $jsonData = $twitter->getMentions(array(
+        'count'     => 5,
+        'trim_user' => true
+    ));
+
+Creating commands
+-----------------
+
+Commands are created using either the ``getCommand()`` method of a client or a magic missing method of a client. Using
+the ``getCommand()`` method allows you to create a command without executing it, allowing for customization of the
+command or the request serialized by the command.
+
+When a client attempts to create a command, it uses the client's ``Guzzle\Service\Command\Factory\FactoryInterface``.
+By default, Guzzle will utilize a command factory that first looks for a concrete class for a particular command
+(concrete commands) followed by a command defined by a service description (operation commands). We'll learn more about
+concrete commands and operation commands later in this chapter.
+
+.. code-block:: php
+
+    // Get a command from the twitter client.
+    $command = $twitter->getCommand('getMentions');
+    $result = $command->execute();
+
+Unless you've skipped ahead, running the above code will throw an exception.
+
+    PHP Fatal error:  Uncaught exception 'Guzzle\Common\Exception\InvalidArgumentException' with message
+    'Command was not found matching getMentions'
+
+This exception was thrown because the "getMentions" command has not yet been implemented. Let's implement one now.
+
+Concrete commands
+~~~~~~~~~~~~~~~~~
+
+Commands can be created in one of two ways: create a concrete command class that extends
+``Guzzle\Service\Command\AbstractCommand`` or
+:doc:`create an OperationCommand based on a service description <guzzle-service-descriptions>`. The recommended
+approach is to use a service description to define your web service, but you can use concrete commands when custom
+logic must be implemented for marshaling or unmarshaling a HTTP message.
+
+Commands are the method in which you abstract away the underlying format of the requests that need to be sent to take
+action on a web service. Commands in Guzzle are meant to be built by executing a series of setter methods on a command
+object. Commands are only validated right before they are executed. A ``Guzzle\Service\Client`` object is responsible
+for executing commands. Commands created for your web service must implement
+``Guzzle\Service\Command\CommandInterface``, but it's easier to extend the ``Guzzle\Service\Command\AbstractCommand``
+class, implement the ``build()`` method, and optionally implement the ``process()`` method.
+
+Serializing requests
+^^^^^^^^^^^^^^^^^^^^
+
+The ``build()`` method of a command is responsible for using the arguments of the command to build and serialize a
+HTTP request and set the request on the ``$request`` property of the command object. This step is usually taken care of
+for you when using a service description driven command that uses the default
+``Guzzle\Service\Command\OperationCommand``. You may wish to implement the process method yourself when you aren't
+using a service description or need to implement more complex request serialization.
+
+.. important::::
+
+    When implementing a custom ``build()`` method, be sure to set the class property of ``$this->request`` to an
+    instantiated and ready to send request.
+
+The following example shows how to implement the ``getMentions``
+`Twitter API <https://dev.twitter.com/docs/api/1.1/get/statuses/mentions_timeline>`_ method using a concrete command.
+
+.. code-block:: php
+
+    namespace mtdowling\Twitter\Command;
+
+    use Guzzle\Service\Command\AbstractCommand;
+
+    class GetMentions extends AbstractCommand
+    {
+        protected function build()
+        {
+            // Create the request property of the command
+            $this->request = $this->client->get('statuses/mentions_timeline.json');
+
+            // Grab the query object of the request because we will use it for
+            // serializing command parameters on the request
+            $query = $this->request->getQuery();
+
+            if ($this['count']) {
+                $query->set('count', $this['count']);
+            }
+
+            if ($this['since_id']) {
+                $query->set('since_id', $this['since_id']);
+            }
+
+            if ($this['max_id']) {
+                $query->set('max_id', $this['max_id']);
+            }
+
+            if ($this['trim_user'] !== null) {
+                $query->set('trim_user', $this['trim_user'] ? 'true' : 'false');
+            }
+
+            if ($this['contributor_details'] !== null) {
+                $query->set('contributor_details', $this['contributor_details'] ? 'true' : 'false');
+            }
+
+            if ($this['include_entities'] !== null) {
+                $query->set('include_entities', $this['include_entities'] ? 'true' : 'false');
+            }
+        }
+    }
+
+By default, a client will attempt to find concrete command classes under the ``Command`` namespace of a client. First
+the client will attempt to find an exact match for the name of the command to the name of the command class. If an
+exact match is not found, the client will calculate a class name using inflection. This is calculated based on the
+folder hierarchy of a command and converting the CamelCased named commands into snake_case. Here are some examples on
+how the command names are calculated:
+
+#. ``Foo\Command\JarJar`` **->** jar_jar
+#. ``Foo\Command\Test`` **->** test
+#. ``Foo\Command\People\GetCurrentPerson`` **->** people.get_current_person
+
+Notice how any sub-namespace beneath ``Command`` is converted from ``\`` to ``.`` (a period). CamelCasing is converted
+to lowercased snake_casing (e.g. JarJar == jar_jar).
+
+Parsing responses
+^^^^^^^^^^^^^^^^^
+
+The ``process()`` method of a command is responsible for converting an HTTP response into something more useful. For
+example, a service description operation that has specified a model object in the ``responseClass`` attribute of the
+operation will set a ``Guzzle\Service\Resource\Model`` object as the result of the command. This behavior can be
+completely modified as needed-- even if you are using operations and responseClass models. Simply implement a custom
+``process()`` method that sets the ``$this->result`` class property to whatever you choose. You can reuse parts of the
+default Guzzle response parsing functionality or get inspiration from existing code by using
+``Guzzle\Service\Command\OperationResponseParser`` and ``Guzzle\Service\Command\DefaultResponseParser`` classes.
+
+If you do not implement a custom ``process()`` method and are not using a service description, then Guzzle will attempt
+to guess how a response should be processed based on the Content-Type header of the response. Because the Twitter API
+sets a ``Content-Type: application/json`` header on this response, we do not need to implement any custom response
+parsing.
+
+Operation commands
+~~~~~~~~~~~~~~~~~~
+
+Operation commands are commands in which the serialization of an HTTP request and the parsing of an HTTP response are
+driven by a Guzzle service description. Because request serialization, validation, and response parsing are
+described using a DSL, creating operation commands is a much faster process than writing concrete commands.
+
+Creating operation commands for our Twitter client can remove a great deal of redundancy from the previous concrete
+command, and allows for a deeper runtime introspection of the API. Here's an example service description we can use to
+create the Twitter API client:
+
+.. code-block:: json
+
+    {
+        "name": "Twitter",
+        "apiVersion": "1.1",
+        "baseUrl": "https://api.twitter.com/1.1",
+        "description": "Twitter REST API client",
+        "operations": {
+            "GetMentions": {
+                "httpMethod": "GET",
+                "uri": "statuses/mentions_timeline.json",
+                "summary": "Returns the 20 most recent mentions for the authenticating user.",
+                "responseClass": "GetMentionsOutput",
+                "parameters": {
+                    "count": {
+                        "description": "Specifies the number of tweets to try and retrieve",
+                        "type": "integer",
+                        "location": "query"
+                    },
+                    "since_id": {
+                        "description": "Returns results with an ID greater than the specified ID",
+                        "type": "integer",
+                        "location": "query"
+                    },
+                    "max_id": {
+                        "description": "Returns results with an ID less than or equal to the specified ID.",
+                        "type": "integer",
+                        "location": "query"
+                    },
+                    "trim_user": {
+                        "description": "Limits the amount of data returned for each user",
+                        "type": "boolean",
+                        "location": "query"
+                    },
+                    "contributor_details": {
+                        "description": "Adds more data to contributor elements",
+                        "type": "boolean",
+                        "location": "query"
+                    },
+                    "include_entities": {
+                        "description": "The entities node will be disincluded when set to false.",
+                        "type": "boolean",
+                        "location": "query"
+                    }
+                }
+            }
+        },
+        "models": {
+            "GetMentionsOutput": {
+                "type": "object",
+                "additionalProperties": {
+                    "location": "json"
+                }
+            }
+        }
+    }
+
+If you're lazy, you can define the API in a less descriptive manner using ``additionalParameters``.
+``additionalParameters`` define the serialization and validation rules of parameters that are not explicitly defined
+in a service description.
+
+.. code-block:: json
+
+    {
+        "name": "Twitter",
+        "apiVersion": "1.1",
+        "baseUrl": "https://api.twitter.com/1.1",
+        "description": "Twitter REST API client",
+        "operations": {
+            "GetMentions": {
+                "httpMethod": "GET",
+                "uri": "statuses/mentions_timeline.json",
+                "summary": "Returns the 20 most recent mentions for the authenticating user.",
+                "responseClass": "GetMentionsOutput",
+                "additionalParameters": {
+                    "location": "query"
+                }
+            }
+        },
+        "models": {
+            "GetMentionsOutput": {
+                "type": "object",
+                "additionalProperties": {
+                    "location": "json"
+                }
+            }
+        }
+    }
+
+You should attach the service description to the client at the end of the client's factory method:
+
+.. code-block:: php
+
+    // ...
+    class TwitterClient extends Client
+    {
+        public static function factory($config = array())
+        {
+            // ... same code as before ...
+
+            // Set the service description
+            $client->setDescription(ServiceDescription::factory('path/to/twitter.json'));
+
+            return $client;
+        }
+    }
+
+The client can now use operations defined in the service description instead of requiring you to create concrete
+command classes. Feel free to delete the concrete command class we created earlier.
+
+.. code-block:: php
+
+    $jsonData = $twitter->getMentions(array(
+        'count'     => 5,
+        'trim_user' => true
+    ));
+
+Executing commands in parallel
+------------------------------
+
+Much like HTTP requests, Guzzle allows you to send multiple commands in parallel. You can send commands in parallel by
+passing an array of command objects to a client's ``execute()`` method. The client will serialize each request and
+send them all in parallel. If an error is encountered during the transfer, then a
+``Guzzle\Service\Exception\CommandTransferException`` is thrown, which allows you to retrieve a list of commands that
+succeeded and a list of commands that failed.
+
+.. code-block:: php
+
+    use Guzzle\Service\Exception\CommandTransferException;
+
+    $commands = array();
+    $commands[] = $twitter->getCommand('getMentions');
+    $commands[] = $twitter->getCommand('otherCommandName');
+    // etc...
+
+    try {
+        $result = $client->execute($commands);
+        foreach ($result as $command) {
+            echo $command->getName() . ': ' . $command->getResponse()->getStatusCode() . "\n";
+        }
+    } catch (CommandTransferException $e) {
+        // Get an array of the commands that succeeded
+        foreach ($e->getSuccessfulCommands() as $command) {
+            echo $command->getName() . " succeeded\n";
+        }
+        // Get an array of the commands that failed
+        foreach ($e->getFailedCommands() as $command) {
+            echo $command->getName() . " failed\n";
+        }
+    }
+
+.. note::
+
+    All commands executed from a client using an array must originate from the same client.
+
+Special command options
+-----------------------
+
+Guzzle exposes several options that help to control how commands are validated, serialized, and parsed.
+Command options can be specified when creating a command or in the ``command.params`` parameter in the
+``Guzzle\Service\Client``.
+
+=========================== ============================================================================================
+command.request_options     Option used to add :ref:`Request options <request-options>` to the request created by a
+                            command
+command.hidden_params       An array of the names of parameters ignored by the ``additionalParameters`` parameter schema
+command.disable_validation  Set to true to disable JSON schema validation of the command's input parameters
+command.response_processing Determines how the default response parser will parse the command. One of "raw" no parsing,
+                            "model" (the default method used to parse commands using response models defined in service
+                            descriptions)
+command.headers             (deprecated) Option used to specify custom headers.  Use ``command.request_options`` instead
+command.on_complete         (deprecated) Option used to add an onComplete method to a command.  Use
+                            ``command.after_send`` event instead
+command.response_body       (deprecated) Option used to change the entity body used to store a response.
+                            Use ``command.request_options`` instead
+=========================== ============================================================================================
+
+Advanced client configuration
+=============================
+
+Default command parameters
+--------------------------
+
+When creating a client object, you can specify default command parameters to pass into all commands. Any key value pair
+present in the ``command.params`` settings of a client will be added as default parameters to any command created
+by the client.
+
+.. code-block:: php
+
+    $client = new Guzzle\Service\Client(array(
+        'command.params' => array(
+            'default_1' => 'foo',
+            'another'   => 'bar'
+        )
+    ));
+
+Magic methods
+-------------
+
+Client objects will, by default, attempt to create and execute commands when a missing method is invoked on a client.
+This powerful concept applies to both concrete commands and operation commands powered by a service description. This
+makes it appear to the end user that you have defined actual methods on a client object, when in fact, the methods are
+invoked using PHP's magic ``__call`` method.
+
+The ``__call`` method uses the ``getCommand()`` method of a client, which uses the client's internal
+``Guzzle\Service\Command\Factory\FactoryInterface`` object. The default command factory allows you to instantiate
+operations defined in a client's service description. The method in which a client determines which command to
+execute is defined as follows:
+
+1. The client will first try to find a literal match for an operation in the service description.
+2. If the literal match is not found, the client will try to uppercase the first character of the operation and find
+   the match again.
+3. If a match is still not found, the command factory will inflect the method name from CamelCase to snake_case and
+   attempt to find a matching command.
+4. If a command still does not match, an exception is thrown.
+
+.. code-block:: php
+
+    // Use the magic method
+    $result = $twitter->getMentions();
+
+    // This is exactly the same as:
+    $result = $twitter->getCommand('getMentions')->execute();
+
+You can disable magic methods on a client by passing ``false`` to the ``enableMagicMethod()`` method.
+
+Custom command factory
+----------------------
+
+A client by default uses the ``Guzzle\Service\Command\Factory\CompositeFactory`` which allows multiple command
+factories to attempt to create a command by a certain name. The default CompositeFactory uses a ``ConcreteClassFactory``
+and a ``ServiceDescriptionFactory`` if a service description is specified on a client. You can specify a custom
+command factory if your client requires custom command creation logic using the ``setCommandFactory()`` method of
+a client.
+
+Custom resource Iterator factory
+--------------------------------
+
+Resource iterators can be retrieved from a client using the ``getIterator($name)`` method of a client. This method uses
+a client's internal ``Guzzle\Service\Resource\ResourceIteratorFactoryInterface`` object. A client by default uses a
+``Guzzle\Service\Resource\ResourceIteratorClassFactory`` to attempt to find concrete classes that implement resource
+iterators. The default factory will first look for matching iterators in the ``Iterator`` subdirectory of the client
+followed by the ``Model`` subdirectory of a client. Use the ``setResourceIteratorFactory()`` method of a client to
+specify a custom resource iterator factory.
+
+Plugins and events
+==================
+
+``Guzzle\Service\Client`` exposes various events that allow you to hook in custom logic. A client object owns a
+``Symfony\Component\EventDispatcher\EventDispatcher`` object that can be accessed by calling
+``$client->getEventDispatcher()``. You can use the event dispatcher to add listeners (a simple callback function) or
+event subscribers (classes that listen to specific events of a dispatcher).

+Events emitted from a Service Client
+------------------------------------
+
+A ``Guzzle\Service\Client`` object emits the following events:
