title: Authentication with Node/Express/Socket.IO
body: <p>I have a node/socket.io/express server that's connected to a HTML file (like <a href="http://socket.io/get-started/chat/" rel="noreferrer">so</a>). So visiting the web address connects you to the server. I am trying to set up a system where by, said server is being run on multiple computers at a time and by way of some sort of username and password authentication, visiting the webpage with specific credentials connects you to one of the computers with those same credentials running the server.</p>
  
  <p>Ive seen mention of "Redis" from previous similar questions but they are pretty old and im wondering if there is a newer or better way of achieving this.</p>
