- ====================
- Backoff retry plugin
- ====================
- The ``Guzzle\Plugin\Backoff\BackoffPlugin`` automatically retries failed HTTP requests using custom backoff strategies:
- .. code-block:: php
- use Guzzle\Http\Client;
- use Guzzle\Plugin\Backoff\BackoffPlugin;
- $client = new Client('http://www.test.com/');
- // Use a static factory method to get a backoff plugin using the exponential backoff strategy
- $backoffPlugin = BackoffPlugin::getExponentialBackoff();
- // Add the backoff plugin to the client object
- $client->addSubscriber($backoffPlugin);
- The BackoffPlugin's constructor accepts a ``Guzzle\Plugin\Backoff\BackoffStrategyInterface`` object that is used to
- determine when a retry should be issued and how long to delay between retries. The above code example shows how to
- attach a BackoffPlugin to a client that is pre-configured to retry failed 500 and 503 responses using truncated
- exponential backoff (emulating the behavior of Guzzle 2's ExponentialBackoffPlugin).
