title: newer chrome fails on websocket using haproxy server
body: <p>test site <a href="http://socket.trailsandtribulations.net" rel="nofollow">http://socket.trailsandtribulations.net</a></p>
  
  <p>firefox: v15 works fine.  (however, if lots of traffic and slow net, firefox will frequently fail as well (quietly).)</p>
  
  <p>chrome: previously worked, but v21 gets <code>Error during WebSocket handshake: 'Connection' header value is not 'Upgrade'</code></p>
  
  <p><em>however</em>, if <code>chrome</code> is running locally, it works fine!  it breaks on my client in Thailand and server in Germany.  again, Firefox works correctly all the time, as did earlier versions of chrome.</p>
  
  <p>using <code>haproxy</code> to split between websockets via <code>node.js</code> and html via <code>nginx</code></p>
  
  <p>has something changed that makes this solution not work?</p>
  
  <p><code>haproxy.cfg</code> now displays the test site link - that way it's always current.</p>
