Enabling same domain restrictions for xmlhttprequest

[Yansky]

Hi, I was wondering if it was possible to enable same domain
restrictions for either the GM_xmlhttpRequest or the regular
XMLHttpRequest object in greasemonkey?

I've tired "new unsafeWindow.XMLHttpRequest();" , but that gave me an
error, so I tried "new window.wrappedJSObject.XMLHttpRequest();" which
didn't give me an error, but also didn't seem to restrict the request
to the same domain.

Is it possible to do this?

Cheers.
