How could GM_xmlhttpRequest fetch the 'Location' in the Response Headers?

How could GM_xmlhttpRequest fetch the 'Location' in the Response Headers?

It displays status:200 when I use GM_xmlhttpRequest, but actually it needs to be 302.

[Redirects are handled transparently](https://dvcs.w3.org/hg/xhr/raw-file/tip/Overview.html#infrastructure-for-the-send()-method), but you can use the finalUrl property of GM_xmlhttpRequest to detect redirects.

var url = "http://google.com";
GM_xmlhttpRequest ( {
    method: "GET",
    url: url,
    onload: function (response) {
        console.debug ('Redirected: ' + (url != response.finalUrl));
    }
} );

Yes it reports:

Redirected: true

How can I get the real redirected URL?

response.finalUrl

response.finalUrl is not the correct Location
