title: CORS not working on Chrome
body: <p>I've set up Cross-Origin Resource Sharing on a server (Jetty using the CrossOriginFilter) and it works perfectly on IE8 and Firefox.  On Chrome, it just ... doesn't.</p>
  
  <pre><code>  $.ajax({ url : crossOriginURL,
      type : "GET",
      error : function(req, message) {
          alert(message);
      },
      dataType :  "json" } );
  </code></pre>
  
  <p>The error function is invoked, with the helpful message "error".  It seems to be making the request, but without any of the headers you'd expect.  If the URL is from the same origin, it works fine.</p>
