Actually, that doesn't bother me too much.
What sort of does is
http://www.mysite.com/irc would point to my IRC applet page, which includes global.php.
I have a subdomain for this at
http://irc.mysite.com. If I was logged in for
http://www.mysite.com/forums/ and went to
http://www.mysite.com/irc, it would retain my being logged in.
If I was logged in
http://forums.mysite.com, and went to
http://irc.mysite.com, it wouldn't see me as logged in. :ermm:
Sort of a bugger, but I guess that's how browsers interpet it.
