As far as I'm aware xhr already follows redirections, and complete isn't
triggered before the final destination is reach (which makes it a lot easier
to ajax a restful app). There is a callback you can set in xhr objects to
handle partial loading events, though I haven't seen the point in using them
in my everyday coding life right now.
