Re: executing a script on browser exit?

None taken :) Using a database: Right now you are using the client to save your session data. You as a programmer have no control over the client side. If you store your session data in a session table, then you have total control over it. You put code on your pages to write to the db when a page is left, perhaps incrementing a value there, among other things. Using persistent connections will reduce the drain on system resources, a drain which is negligble when compared to writing and searching text files. Include a timestamp value in the database, and for any timestamps over some interval, you can write the page counter to a separate, more permanent table, and delete that session record in the session table.
