    // use Symfony\Component\HttpFoundation\Session\Session;

    public function indexAction(Request $request)
    {
        $session = $request->getSession();
    
        // store an attribute for reuse during a later user request
        $session->set('foo', 'bar');

    // To retrieve the session, add the SessionInterface type-hint to your argument and Symfony will provide you with a session
    public function indexAction(SessionInterface $session)
    {
        // store an attribute for reuse during a later user request
        $session->set('foo', 'bar');
    
        // get the attribute set by another controller in another request
        $foobar = $session->get('foobar');
    
        // use a default value if the attribute doesn't exist
        $filters = $session->get('filters', array());
    }
