when user enters your web directly from URL line in browser or bookmarks, no
referer is set. If it enters your page via clicking on other page, referer
is set to the other page. Unless the user has browser plugin or proxy that
restricts referer from being sent (yes, that happens).

That is nearly everything you can get at thsi level. You can also set some
cookies and track them, but disabling cookies (for your site) is even easier
than disabling referer.

There is nothing like that in whole HTTP protocol, therefore nothing like
that in apache. HTTP is designed for transferring HTTP objects, and is does
not support sessions, pages, etc. IT's browser who requests for content and
man provide infromations like referer, cookies and user-agent to the server.

Think carefully what will you expect from your users and their browsers -
by implementing useless requirements you can even loose them.
