Incrementing a counter for every page viewed

[amykhar]

If I wanted to increment a counter every time a user (registered or not) viewed a page, what would be the best way to go about it?

Example, person hits the forumhome page. counter= 1. Person clicks a forum link and goes to the forum display page - counter = 2. Person clicks the link to go to the last post in a thread - counter = 3. Person goes back to forumhome page - counter = 4. And so on.

I'm just not sure the best way to carry the counter around without making it visible on the url, which I definitely don't want.

Thanks,
Amy
