title: user authentication using socket.io
body: <p>I've red this tutorial: <a href="http://howtonode.org/socket-io-auth">http://howtonode.org/socket-io-auth</a>.
  It shows how to authenticate users using express and socket.io.
  But is there a way to authenticate users using only socket.io without the need for express?</p>
  
  <p><strong>edit:</strong></p>
  
  <p>For session handling I use RedisStore (<a href="https://github.com/LearnBoost/Socket.IO/wiki/Configuring-Socket.IO">https://github.com/LearnBoost/Socket.IO/wiki/Configuring-Socket.IO</a>).
  Whats left is a module to create authentication cookies.
  Does anyone know of a socket.io implementation I can use to create an authentication cookie like you can do with session handling?</p>
