jquery getResponseHeader always returns 'undefined'?

Question

I have a a form that I am submitting via ajax. I am using the jquery form plugin. What I am trying to do is get the \'Location\' header which is returned from my server.

Answer 1

An XMLHttpRequest will transparently follow a redirect, so the final request won't have the header, it's already followed that redirect and you're seeing the response headers from that request (not the initial request which had the Location header).
