title: how to scale a socket.io application on multiple servers?
body: <p>I have read a lot of stuff about custering, redis but I could not find any real sample.</p>
  
  <p>I have a simple socket.io application and I need to scale this application to many servers.</p>
  
  <p>Looks like socket.io and RedisStore is the solution.</p>
  
  <p>Does anyone has a real world nippet on how he uses socket.io on many servers ?</p>
