/**
 * Clears the Symfony HttpCache proxy between tests
 *
 * The webserver with Symfony is to be started with the WebServerListener.
 *
 * You can define constants in your phpunit to control how this test behaves.
 *
 * To define constants in the phpunit file, use this syntax:
 * <php>
 *     <const name="WEB_SERVER_PORT" value="8080" />
 * </php>
 *
 * WEB_SERVER_PORT     port the PHP webserver listens on (required)
 * WEB_SERVER_HOSTNAME hostname where your application can be reached (required)
 *
 * Note that the SymfonyProxy also uses a SYMFONY_CACHE_DIR constant.
