Changing Symfony Behavior Using AJAX Actions

Question

Assuming I have an application that uses a lot of AJAX requests.

Is there a way to edit Symfony's behavior and automatically call indexAjaxActioninstead indexActionwhen my request was created by AJAX?

I already know that I can check if the Ajax request is using the method Request::isXmlHttpRequest(), but I want it to be automatic (i.e. without testing in each controller).

Already doing a service / package?

Example:

<?php 

use Symfony\Bundle\FrameworkBundle\Controller\Controller;

class FooController extends Controller
{
    public function indexAction($vars)
    {
        $request = $this->getRequest();         
        if($request->isXmlHttpRequest()) {
            return $this->indexAjaxAction($vars);
        }
        // Do Stuff
    }

    public function indexAjaxAction($vars){ /* Do AJAX stuff */ }
}

becomes

<?php 

use Symfony\Bundle\FrameworkBundle\Controller\Controller;

class FooController extends Controller
{
    public function indexAction($vars) { }
    public function indexAjaxAction($vars) { }

    // Other functions
}

            $action = preg_replace(
                '/^(.*?)Action$/', 
                '$1AjaxAction', 
                $controller[1]
            );

            try {
                $r = new \ReflectionMethod($controller[0], $action);

                return $this->doGetArguments(
                    $request, 
                    $controller,

                // Do nothing
            }
        }

        return parent::getArguments($request, $controller);
    }
}

youractionAjaxAction, , , ( );

...

if (is_array($controller) && $request->isXmlHttpRequest()) {
    $controller[1] = preg_replace(
        '/^(?P<action>.*?)Action$/', 
        '$1AjaxAction', 
        $controller[1]
    );
}

return parent::getArguments($request, $controller);

.., , , , , XmlHttpRequest, AjaxAction.
