I have some ideas on this but was wondering if anyone had a way to do this that was better.

Essentially, I have a situation where I don't want the user to be able to access a page via bookmark, only from a referring page within the same drupal site.

My thoughts were to use drupal_preprocess_theme, check the referring url and if the required url, then provide the full theme, if not, then serve an empty "access denied" theme.

I don't think the theme layer itself is the place to put this logic.

Is there a nice function out there that returns the referring url?

Thanks for any insight.
