   2 <body onload="setTimeout(test, 100);">
   3 This test does the following:<br>
   4 1. Load a page, trigger an XHR.<br>
   5 2. Reload the page.<br>
   6 3. Dump the http readers for the reload of the XHR.<br><br>
   7 The XHR is trigger after onload has fired. There should not be an HTTP_CACHE_CONTROL header forcing reload, so an http cache
   8 could load the resource without contacting the server.<br>
   9 The test passes if there is no HTTP_CACHE_CONTROL header displayed below.<br>
