Hi Could anybody tell me how to install a conditional SiteRoot (I would like the SiteRoot only for anonymous users)? Background: I'm running Zope/Plone behind Apache and use ProxyPass and SiteRoot to get some subdirectories from Zope, while the rest of the subdirectories are standard html-pages delivered by Apache. To accelerate this system, I use Apache's mod_cache. This works fine and gives some extra speed. The users see the cached pages under http://mydomain/foo/bar and Plone-Members can login and admin at the system at http://mydomain/extraprefix/foo/bar But if a user now logs in and enters http://mydomain/extraprefix/foo/bar with the SiteRoot, he is redirected to http://mydomain/foo/bar cached by Apache and therefore there is no more Plone-line to edit the page etc. Therefore I had to switch off the cache again. Thanks a lot in advance for any help Michael
