title: ZeroMQ usage in web application: how frontend interacts with backend
body: <p>I heard some facts about ZeroMQ, and I think it's very powerful thing. But now I try to imagine how it can be applied in web application.</p>
  
  <p><em>Could you make an example of using ZeroMQ in web applications?</em></p>
  
  <p>So, the first that strikes me - simple chat application. So, we need frontend and backend. I prefer using python+Tornado as backend. There is python lib for using ZeroMQ. It's clear. So, the next thing is frontend. In frontend I will use some javascript to interact with backend.</p>
  
  <p><em>So, to do this I should use ajax calls, right? Are there some other ways to do it?</em></p>
  
  <p>TIA!</p>
