title: jQuery $.ajax extension XDomainRequest onprogress
body: <p><strong>The short version:</strong></p>
  
  <p>I want to get <a href="https://github.com/kpozin/jquery-ajaxprogress#readme" rel="nofollow">this</a> to work with <a href="https://github.com/Ovea/cors/blob/master/src/main/resources/com/ovea/cors/jquery.ie.cors.js" rel="nofollow">this</a>: </p>
  
  <p><strong>The long version:</strong></p>
  
  <p>I want to create a jQuery extension that adds a progress method to the $.ajax object and which works with IE8 &amp; IE9's XDomainRequest object.</p>
  
  <p>Currently, using the above plugins, I can only define progress event callback handlers for XMLHttpRequest objects.</p>
  
  <p>However, XDomainRequest also provides an onprogress event. I basically need a wrapper for XDomainRequest. Eg. progressEvent.length would correspond to xdr.responseText.length.</p>
  
  <p>I'd appreciate any suggestions on where to begin.</p>
