title: How does Google Analytics Real Time work?
body: <p>I'm wondering how Google Analytics Real Time user interface works, what's the technique ? Do they use long-polling from the client to keep the UI statistics instantly up to date by delivering realtime information from the server to the client?
  I just open Chrome dev tool on network tab and there is a infinite request on <a href="https://www.google.com/analytics/realtime/bind" rel="nofollow">https://www.google.com/analytics/realtime/bind</a>
  Does anybody know the trick? It works flawless...</p>
