Well I work in the Financial Services industry and I've never heard of a requirement like that - generally we trust our users.
If you want such a restrictive policy, then the best way to implement this is as I mentioned earlier 1) When user logs in, set a flag in your DB 2) When a) The user navigates away from the site (its up to you to determine this) b) The user logs out c) The users session times out You need to set the flag to 0 There really isn't another suitable way to to this - you need to centrally store the fact that a particular user has logged on, and the best place for this is a DB. Due to the stateless nature of web apps, you can never tell *exactly* when a user finishes using your site, so the solutions are all workarounds. However, if you are implementing such a restrictive policy, I would suggest that implementing another policy of "click log out when you finish using the site" would solve most of your problems re: determining when a user stops using a site.
