note 54663 deleted from ref.session by danbrown

Note Submitter: jentulman at NOSPAM dot jentulman dot co dot uk ---- Here's one for the 'session disapearing after a rediredt problem'. It's nice and simple but drove me mad for a couple of hours. I was getting reports of users logging in apparently successfully but not actually being logged in and couldn't replicate it myself. I had a configuration file called at the begining of my script setting defines for physical and url paths, and users with the problem were coming in on a domain alias so of course the login went fine, but then they were redirected to a different domain and the cookie was pointless. Not very technical I know but maybe it'll stop someone having to headbang like I did.
