I think that you will be unable to accomplish this in an effective, useful
and reliable manner. This simply isn't the way HTTP works.
But in any case, I don't agree that it would necessarily be wise to be able
to end a session if the user leaves the site. Unless you're concerned about
people visiting your site from shared computers, it strikes me as overkill
to force a user to login again after going to another page.
