Override Symfony2 Original Request Class

Have you ever wanted to override Symfony2 core Request class?
I am the one of them. Actually what I have would liked to do is overriding isSecure method in Request class bceause of our server configuration was a bit tricky.

I have googled a bit and found useful article on Symfony2 ofiicial document.
It says "you should use setFactoryMethod". HOWEVER "The setFactory() method was added in Symfony 2.4".
I have used Symfony2.3.X because that version has long maintenance term.

I have googled and finally found the solution for Symfony 2.3.X.
You just modify request creation part in web/app.php (and web/app_dev.php).

require_once __DIR__.'/../app/AppKernel.php';
//require_once __DIR__.'/../app/AppCache.php';

$kernel = new AppKernel('prod', false);
$kernel->loadClassCache();
//$kernel = new AppCache($kernel);

// You should modify here...
// ORIGINAL
// $request = Request::createFromGlobals();
// I have added my original request class. class and method name should be what you prepared.
$request = MyRequest::createFromGlobals();

$response = $kernel->handle($request);
$response->send();
$kernel->terminate($request, $response);

That's it! Quite easy! However if you know much better solution, please feel free to put comments ;)
Also the next question is coming up for me - "What about overrding Response class?".
Will investigate and hope write a post.
