title: IE8/9 AJAX/CORS (XDomainRequest) send referer header
body: <p>I'm using <code>XDomainRequest</code> in IE8 &amp; 9 to send requests to a server. With <code>XMLHttpRequests</code> in other browsers, both an <code>Origin</code> and <code>Referer</code> header are sent, and could look like this:</p>
  
  <pre><code>Origin: http://www.example.com
  Referer: http://www.example.com/mypage/index.htm
  </code></pre>
  
  <p>But <code>XDomainRequest</code> only sends the Origin (so I don't see the full calling URL). Is there a way to force it to also send the Referer? I'm trying to avoid sending it as a query string or POST parameter.</p>
  
  <p>I know that <code>XDomainRequest</code> doesn't allow custom headers, but I'm hoping that because Referer is a standard header there might be some way to enable it.</p>
