ajax CORS with Internet Explorer 9

Question

I want to do cross domain ajax calls with custom header and cookies . I did it with CORS which works with Chrome, Firefox and IE 10 and 11.

How can I get it to work in IE 9?

Note: I need custom headers and cookies.

If your request are just GET and POST, you can use the XDomainRequest: http://blogs.msdn.com/b/ieinternals/archive/2010/05/13/xdomainrequest-restrictions-limitations-and-workarounds.aspx

There is a plugin for jQuery $.ajax: https://github.com/MoonScript/jQuery-ajaxTransport-XDomainRequest

If you want to use the full CORS capabilities (es: call REST services with a backbone.js fronted, use PUT and DELETE methods) sadly you cannot support IE 9.
