 /**
  * automatic supplement of library for redirects
  *
  * @see lithium\net\http\Router::match()
  * @see lithium\action\Controller::$response
  * @see lithium\action\Controller::redirect()
  * @param mixed $url The location to redirect to, provided as a string relative to the root of
  *              the application, a fully-qualified URL, or an array of routing parameters to be
  *              resolved to a URL. Post-processed by `Router::match()`.
  * @param array $options Options when performing the redirect. Available options include:
  *              - `'status'` _integer_: The HTTP status code associated with the redirect.
  *                Defaults to `302`.
  *              - `'head'` _boolean_: Determines whether only headers are returned with the
  *                response. Defaults to `true`, in which case only headers and no body are
  *                returned. Set to `false` to render a body as well.
  *              - `'exit'` _boolean_: Exit immediately after rendering. Defaults to `false`.
  *                Because `redirect()` does not exit by default, you should always prefix calls
  *                with a `return` statement, so that the action is always immediately exited.
  * @return object Returns the instance of the `Response` object associated with this controller.
