title: Is it possible to update a browser based on an event in webserver?
body: <p>When an event occurs in the webserver, I want the open browser of my application to know about it. The obvious way would be to have a jquery ajax call every minute to the web server to check if anything has changed. </p>
  
  <p>Based on my understanding of how the web works, you cannot get an HTTP response (or an xmlhttp response for ajax calls) without an HTTP (or XMLHTTP ) request originating from the browser. Is that correct?</p>
