[Zope] Accelerated HTTP Cache Manager doesn't use SiteRoot?

I'm a Squid newbie, but at least seem to have it working with my Zope site. However, I have a CMF site that is being served as the virtual root of the site (via Apache Rewrite/Virtual Host Monster), so there's a SiteRoot object in the root of the CMF site. The Cache Manager is also in the root of the CMF site, and is set to notify the Squid URL of purges, but the purge requests are relative to the root of Zope, not SiteRootPATH, so don't match the Squid cache URLs. Any help appreciated. -- David Chandek-Stark Web Applications Developer Duke University - Perkins Library (919) 660-5859 dc@duke.edu
