 /**
  * This method defines the workflow from the HTTP Request and ends with a Response.
  * HttpKernel allows us to use event listeners and does the work by dispatching those events.
  * Basically we are creating an EventDispatcher and a controller resolver in this handle method.
  *
  * @param Request $request The Request instance
  * @param int     $type    The default type request [MASTER_REQUEST = 1, SUB_REQUEST = 2]
  * @param bool    $catch   The option to catch exceptions or not
  *
  * @throws \ResourceNotFoundException When a controller not found occurs during processing
  * @throws \Exception When an Exception occurs during processing
  *
  * @return Response The current Response interface
  *
  * @api
