title: SCRIPT5: Access is denied in IE9 on xmlhttprequest
body: <pre><code>var xhttp=new XMLHttpRequest();
  xhttp.open('GET', 'foo.xml', false);
  </code></pre>
  
  <p><kbd>F12</kbd> pops back: SCRIPT5: Access is denied. on Line 95, which is the xhttp.open line.</p>
  
  <p>My JavaScript seems well-formed, and Firefox does what I think it should.</p>
  
  <p>I've read a lot of questions very similar to this one, so I've checked out the Same Origin Policy, but I can't see how it'd apply considering foo.xml is in the same directory as the html file. I opened up the scripting permissions on my local intranet, and told McAfee to take a five-minute break, just to be sure. I even tried running IE as admin, so this can't really be a permissions issue can it? Why else would IE be denied access to a local file?</p>
