So- I've got this ajax request, see-. Blonde, about 6 feet tall, looks like this:

```
$.ajax({
    url: 'http://example.com/makeThing',
    dataType: 'html',
    type: 'POST',
    data: {
        something:someotherthing
    },
    complete: function(request, status) {
        console.log("headers=" + request.getAllResponseHeaders(););
    }
});

```

What happens is that the request to '/makeThing' returns a 302 redirect to a second url:'getThing/abc123'. All I want to do is find out what that second url is (programmatically- it'll be different every time, so just checking in firebug doesn't help me). I've tried plumbing the response headers that come back to the 'complete' callback, but that just gives me what came back on the second request.

Constraints:
-I have no control over the server this is running on- just the js.
-Can switch frameworks if I have to (dojo? prototype?)

Ideally, I'd do some sort of header-only request to /makeThing to find out what the redirect url is by getting just the headers of the initial 302 response.

Failing that (since jquery auto-follows redirects and doesn't seem to have a way to step in between the requests), I get retrieve the final response and use it to somehow get the url from... something? The request object, maybe?

TLDR: Sending an ajax request. Framework auto-follows the resulting 302 redirect. How do I figure out where it redirected to?

EDIT, Clarification:
The final url will be different every time- calling 'makeThing' causes the server to create what is thereafter hosted at 'getThing/abc123'
