So? Who is talking about "logged in"? I am talking about PHP sessions.

Rubbish.

So what if they are? They are still connected and have a session. Of
course we can not know if that user is actually LOOKING - but they *ARE*
connected.

Yes you can. Because even if they are not physically looking, they ARE
still browsing. Sure, we dont know if the use is asleep or on the toilet
but he IS still maintaining a session.

context of a PHP site.
