javascript withcredentials Setting headers in XDomainRequest or ActiveXObject('Microsoft.XMLHTTP')

xdomainrequest withcredentials (1)

Referring to this post See the point three 3. No custom headers may be added to the request

You cannot add custom headers to an XDR object. Hope this helps.

I'm trying to do something like this (W3 compliant, DOM):

xhr.setRequestHeader( 'X-Requested-With', 'XMLHttpRequest' );

For ActiveXObject('Microsoft.XMLHTTP') and XDomainRequest (IE8). I'm having no such luck finding it anywhere in microsoft documentation or even google. Any idea how I can achieve this?
