I'm trying to use microsoft XDomainRequest to send cross domain request. Here is the code

...
if ($.browser.msie && window.XDomainRequest) {
  // Use Microsoft XDR
  var xdr = new XDomainRequest();
    xdr.open("POST", "http://graph.facebook.com/1524623057/");

  xdr.send();
} 
 ....

It gives SCRIPT5: Access is denied. error on xdr.open(...) line.

I found the reason of this problem. As stated in Point 7:

Requests must be targeted to the same scheme as the hosting page

This restriction means that if your AJAX page is at http://example.com, then your target URL must also begin with HTTP. Similarly, if your AJAX page is at https://example.com, then your target URL must also begin with HTTPS.
