 * Zend_Controller_Request_Apache404

 *

 * HTTP request object for use with Zend_Controller family. Extends basic HTTP

 * request object to allow for two edge cases when using Apache:

 * - Using Apache's 404 handler instead of mod_rewrite to direct requests

 * - Using the PT flag in rewrite rules

 *

 * In each case, the URL to check against is found in REDIRECT_URL, not

 * REQUEST_URI.
