Basicly what I'm doing is wrapping xcache functions so the username/password for xcaches admin functions can be hardcoded into the xcache module and doesn't conflict with the phpBB3 Apache auth module if it's being used.
Or so I thought.
I'm not so sure I need to do this now though. I'm wondering if I can just overwrite the PHP_AUTH_USER and PHP_AUTH_PW variables at the beginning of the request and the browser will automaticly reset them on the next page request.
Should I reset those two variables like I've done in revision-11 of that diff file, or should I just overwrite them in the beginning of the program flow and rely on the browser to resend the ones for the forum auth ?
