Cross-Domain AJAX for IE8

Implements automatic Cross Origin Resource Sharing support using the XDomainRequest object for IE8 and IE9 when using the ajax function in jQuery 1.5+.

CORS requires the Access-Control-Allow-Origin header to be present in the AJAX response from the server.

In order to use XDomainRequest in Internet Explorer, the request must be: - Only GET or POST - When POSTing, the data will always be sent with a Content-Type of text/plain - Only HTTP or HTTPS - Protocol must be the same scheme as the calling page - Always asynchronous
