Weird behavior when checking the existence of a cookie

Hmmm... that's not really an option. The upstream does not know that it's
under a subdir of the domain (and the devs insist that it shouldn't be
coupled to that).

Also, if the cookie detection lines are commented out, the proxy_pass (w/
the ending forward slash) works as expected.

This specific behavior (cookie detection affecting proxy_pass) seems rather
inconsistent. =/

Other than that the requirements are similar to the thread named "Rewriting
location directive by upstream servers".

Thanks :D
