[Zope] getting the URL of the request....

[Rustad, Aaron]

Can anyone tell me how to get the URL that was clicked in order to get to a
certain page? What I mean by this is, I have an edit contents link that
points to: http://address/medicine/clinical/folder_contents (Obviously in
CMF, this
brings up the contents of the "clinical" directory).  However, when the page
is rendered, the id absolute_url is just http://address/medicine/clinical
and for functional reasons, I need to know if the page was rendered with
"folder_contents". Any suggestions?
Thanks!
Aaron.
