When calling a sub-request via something like:

$url = 'some/local/route';
$response = Request::factory($url)->execute();

If the controller action the $url maps to contains an unconditional

$this->request->redirect($somewhere);

In the original action/request $response will not be an instance of Response.

This means you can't verify that the result of the sub-request was successful with something like:

 if($response->status() == 200)
     // do happy stuff
 else
     // so sad stuff
