Session dont get data (only the ID)
Hi,

Im trying to share session data beetwen the socket server and Symfony using handlers (File) but he get only the session id:

My socket file:

``` php
        $loop   = \React\EventLoop\Factory::create();
        $pusher = new \Comunicacao\ComunicadorBundle\Topic\WampChatTopic();

        // Listen for the web server to make a ZeroMQ push after an ajax request
        $context = new \React\ZMQ\Context($loop);
        $pull = $context->getSocket(\ZMQ::SOCKET_PULL);
        $pull->bind('tcp://127.0.0.1:5555'); 
        $pull->on('message', array($pusher, 'onChatMessage'));

        $webSock = new \React\Socket\Server($loop);
        $webSock->listen(8080, '0.0.0.0'); 

        $session = new SessionProvider(
            new \Ratchet\Wamp\WampServer($pusher)
          , new Handler\NativeFileSessionHandler()
        );

        $webServer = new \Ratchet\Server\IoServer(
            new \Ratchet\Http\HttpServer(
                new \Ratchet\WebSocket\WsServer(
                    $session
                )
            ),
            $webSock
        );

        $loop->run();
```

On the topic implementation have:

``` php
        public function onOpen(ConnectionInterface $conn) {
            print_r($conn->WebSocket->request->getCookies());
        }
```

i get de session id (are the same on browser) but the data? nothing...
