[Zope-dev] How to add a SessionID to each page

Hi, I would like to add a SessionID at the end of each requested URL because I would like to know which pages were requested by one user in one session. For example like AMAZON does it: www.amazon.com/books?SessionID=123456 <http://www.amazon.com/books?SessionID=123456> My problem: There are to many pages belonging to my homepage that I can't rewrite each link like: <a href="next_page?SessionID=<dtml-var SessionID>">next_page</a> Also I tried to pass a SessionID with the help of SiteAccess but a automatic insertion of a random ID doesn't work at my machine. Could anyone give me please a helping hand? (Also, excuse my English) Thanks, Hannes
