title: Socket.io NOT emitting messages to XHR Clients
body: <p>Okay, so I've got a Node.js server running Socket.io. It uses a RedisStore so I can have multiple Node.js server instances. Everything works exactly as it should with the exception that I can't emit a message from the server to my XHR-Polling client. It works in fine in the following situations:</p>
  
  <ul>
  <li>When testing the client in Chrome and use Websockets it works great.</li>
  <li>When connected to the same Node server instance.
  <ul>
  <li>It should work regardless of which instance its on since I'm using the RedisStore.      </li>
  </ul></li>
  </ul>
