title: Securing channels with nginx and http push module
body: <p>I was able to setup nginx as a message server for building a real-time javascript application with Dojo. For the setup I used the nginx <strong>http_push_module</strong> which can be configured to handle publish/subscribe requests on different “channels”. Channels is “<em>A resource representing an isolated pathway for message transmission. Each channel has a single unique message queue</em>”.
  Channels are identified by a id parameter in the url used within the XHR requests.</p>
  
  <p>I'm in the need of implementing some sort of private channel, which the application can use to push messages to the users, but I've no idea of how to implement channel authentication.</p>
  
  <p>Does anybody ever used http_push_module to create private channels or have suggestions about implementing them?</p>
  
  <p>Thanks in advance for your support.</p>
