title: AJAX inside IFRAME not working against same server
body: <p>I'm using a website, <code>abc.com</code>, that is hosting an <code>iframe</code> of a page on <code>123.com</code>.<br>
  The page inside the <code>iframe</code> is doing an AJAX request to another page on <code>123.com</code>, but we're seeing that the request is getting cancelled.  </p>
  
  <p>Unless I'm wrong — <em>and I haven't found any official information on the internet about this</em> — the call should work fine as it is not a cross-domain request. </p>
  
  <p>Would the fact that the parent frame is on a different domain really hinder the <code>iframe</code> from doing AJAX requests to its own server?</p>
