Basically, how does this work: http://www.stream-hub.com/demo/RealTimeChart/index.html

They are streaming JS through an iframe continuously and the browser window does NOT show the page as “loading”. How did they do that? The streaming part is easy, but how do they prevent the browser window from being in a continuous “loading” state?

Thanks!

    Figured it out. The idea is to create the iframe programatically like so:

    function setupAjax()
{      
  var iframe = document.createElement("iframe");      
  iframe.src = "push.php";
  iframe.style.display = "none";    
  document.body.appendChild(iframe);  
}

    and then.. <body onload="setupAjax()">
