You can't. A visitor will download a document once (and then 'disconnect')
and this is all you could read from your server logs. Some users click away
quickly, some leave it open without looking at it, while others read it
word for word. With JS you could log when the document is closed, but this
cannot differ between case 2 and 3.

What you often see on websites (this seems to be a standard feature of
bulletin board, not sure if other kinds of sites are infected, too) is a
very rough and inaccurate approximation: the number of sessions with
activity in the last X minutes (X about 5).
