How to get jQuery/AJAX final URL

When I run $.get or .load in jQuery, the request seems to follow 302 redirects perfectly fine and gives me ultimate开发者_StackOverflow response, which I can use in the callback for $.get or which plugs into the this element for .load.

While I obviously have the original URL since I am in control of the string that's entered as the first argument in $.get or .load (it would also be helpful if I could get this directly in the callback to simplify things), how can access the final (after redirect) URL in the callback?

I suspect that it would be in the XMLHttpRequest object, for which I have found the specification.

It appears you cannot. You can get the original src, but then you cannot due to security issues.
