The cross domain JSONP type request doesn't use the XMLHttpRequest
object/system. Indeed it couldn't because XMLHttpRequest can't be done
across domains (at least not yet, standards are being formulated).
What happens is that a script tag with the requested URL is inserted
in the document, so no headers can be set.
You'll have to use a "proxy" on a local server, ie:
