Hello list, I already put my question on the "zope@zope.org" list, but there was no solution in sight, so I'm trying to get deeper (spell: start using) into python. I cannot use SiteAccess (because I need multiple ZCatalogs), and my Zope server (port 8080) is behind squid (in http-accelerated mode - port 80). What I would need is changing the hostname and port in the html-responses like this: http://localname.com:8080/blah to http://officialserver.com/blah , so the client reconnects to squid, not zope itself. Any hints where to start looking for the right python files or even functions/methods? Thanks in advance for your info, Martin
