Symfony Session Handler for Ratchet

Question

I'm trying to get Ratchet to work with Memcache/Symfony sessions but I can't get it to work.

App runs without any error but I can't seem to get or set session variables. The socket server and apache wont communicate, even if I specify session handler on the page itself (same on both ends)

Server:

use Ratchet\Server\IoServer;
use Ratchet\Http\HttpServer;
use Ratchet\WebSocket\WsServer;
use Ratchet\Http\Router;
use Ratchet\Wamp\WampServer;
use Ratchet\Session\SessionProvider;
use Ratchet\MessageComponentInterface;
use Ratchet\ConnectionInterface;
use Symfony\Component\Routing\RouteCollection;
use Symfony\Component\Routing\Route;
use Symfony\Component\Routing\RequestContext;
use Symfony\Component\Routing\Matcher\UrlMatcher;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Session\Session;
use Symfony\Component\HttpFoundation\Session\Storage\Handler;
use Symfony\Component\HttpFoundation\Session\Attribute\NamespacedAttributeBag;
use Symfony\Component\HttpFoundation\Session\Storage;
use Symfony\Component\HttpFoundation\Session\Storage\NativeSessionStorage;
use Ratchet\App;

ini_set('session.cookie_domain', '.domain.com:80');
ini_set('session.save_handler', 'memcache');
ini_set('session.save_path', 'localhost:11211');

session_start();

require dirname(__DIR__) . '/vendor/autoload.php';

$storage = new NativeSessionStorage(array());
$session = new Session($storage, new NamespacedAttributeBag());

$request = Request::createFromGlobals();
$request->setSession($session);

$memcache = new Memcache;
$memcache->connect('localhost', 11211);

$session = new SessionProvider(
    new \App\Mire
  , new Handler\MemcacheSessionHandler($memcache)
);

$server = new Ratchet\App('www.domain.com', 8081, '0.0.0.0');
$server->route('/sess', $session);
$server->run();

App:

namespace App;

use Symfony\Component\HttpFoundation\Session\Storage\Handler;
use Ratchet\App;
use Ratchet\MessageComponentInterface;
use Ratchet\ConnectionInterface;
use Ratchet\Session\SessionProvider;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Session\Session;
use Symfony\Component\HttpFoundation\Session\Attribute\NamespacedAttributeBag;
use Symfony\Component\HttpFoundation\Session\Storage\NativeSessionStorage;

class Mire implements MessageComponentInterface {
    protected $clients;

    public function __construct() {
        $this->clients = array();
    }

    public function onOpen(\Ratchet\ConnectionInterface $conn) {
        $this->clients[$conn->resourceId] = $conn;
        echo "New connection! ({$conn->resourceId})\n";

        $sessao = new \Symfony\Component\HttpFoundation\Session\Session(new \Symfony\Component\HttpFoundation\Session\Storage\PhpBridgeSessionStorage());
        $sessao->start();

        echo "io:".$conn->Session->get("io");
    }

    public function onMessage(ConnectionInterface $from, $msg) {
    }

    public function onClose(ConnectionInterface $conn) {
        unset($this->clients[$conn->resourceId]);
        echo "Connection {$conn->resourceId} has disconnected\n";
    }

    public function onError(ConnectionInterface $conn, \Exception $e) {
        echo "An error has occurred: {$e->getMessage()}\n";
        $conn->close();
    }
}

Can you help me get both ends to communicate?

You need to run your webserver and websocket server on the same port, otherwise the cookie cannot be shared (so you need to run the websocket on a different server than the webserver)
