title: Realtime websocket-like behavior possible on Heroku?
body: <p>I am considering making a chess app in Rails where moves need to be pushed from the server to the client browser asynchronously (ideally with websockets).</p>
  
  <p>However, from what little research I've done it appears that Heroku does not support websockets. But there is an alternative in using socket.io configured to use long polling instead of websockets.</p>
  
  <p>Is long polling insufficient to achieve latency requirements for something like a 5 minute blitz game of chess?</p>
