Or if they hit the back button.
Or if they choose one of their favourites.
Or if they type in a new URL in the address bar.
Or if they right click and choose to open the link in a new tab/window.
Or if they simply wander off to the pub because the power has failed.
You can *never* tell when somebody leaves a site.

What script? Where? On the client? On the server? On the new page?
Surely not on the old page, that has long since gone.
And if the viewer chooses to [right-click > open in a new tab] on that link?
You will never know. Neither "site" will know. The web is stateless. You do
*not* know what has happened previously.
