AJAX - Get response URL after redirect

Question

I was wondering if there is a way to get the URL of the returned resource after a AJAX call in JavaScript?

I want to use this with a form, which is in \"mysite.com/u

Answer 1

Solved this by setting the response header "Location" in a Java Filter.

  HttpServletRequest httpRequest = (HttpServletRequest) request;
  HttpServletResponse httpResponse = (HttpServletResponse) response;
  String path = httpRequest.getRequestURI();
  httpResponse.setHeader("Location", path);

In JavaScript I could then use

  XMLHttpRequest.getResponseHeader("Location")

Hopefully this won't cause any unforeseen problems. :P

If anyone else have an easier solution though I'd like to see it.
