logic in cgi/session, but i can't seem to find where it actually uses
fyi, i'm asking because i'm having an issue where i set the user during
login, but the redirect following the login is using (or creating) a
different session. it happens intermittently, not every time, so
poking around for some clues. thanks in advance!
