Redirect Symfony2 LogoutSuccessHandler to original logout target

Question

I need to modify my user object on logout. To do this, I have a security.yml that contains the following (amongst other things) -

#...
    logout:
        s

So, I think I've figured out the right answer -

Rather than implementing LogoutSuccessHandlerInterface and configuring a logout.success_handler, my security.yml now looks like this -

# ...
logout:
    handlers: [my.bundle.security.logout_handler]
# ...

...and I'm implementing Symfony\Component\Security\Http\Logout\LogoutHandlerInterface. Confusing naming, but this seems to be the preferred way of doing post-logout operations without having to get involved with the response object. My implementation looks like this -

namespace My\Bundle\Security;

use Symfony\Component\Security\Http\Logout\LogoutHandlerInterface;
use Symfony\Component\Security\Core\Authentication\Token\TokenInterface;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\HttpFoundation\Request;
use Doctrine\ORM\EntityManager;

/**
 * Do post logout stuff
 */
class LogoutHandler implements LogoutHandlerInterface
{

    /**
     * @var EntityManager
     */
    protected $em;

    /**
     * Constructor
     * @param EntityManager $em
     */
    public function __construct(EntityManager $em)
    {

        $this->em = $em;
    }

    /**
     * Do post logout stuff
     */
    public function logout(Request $request, Response $response, TokenInterface $authToken)
    {
        $user = $authToken->getUser();

        // do stuff with the user object...
        $this->em->flush();

        return $response;
    }
}

...as you can see, the LogoutHandlerInterface provides a pre-made $response object that I can just return when I'm finished.
