Or smth. completely different?

Good questions all of them ;-)

My goal is to have the script run once when the user accesses the main forum page but not again until perhaps the session expires to reduce dns lookups. I'm going to assume a browser session is until the browser is closed and vBulletin Session is until the cleanup occurs. Of course I really don't know I'm just guessing. Perhap you can suggest some options.
