I now feel ZCache might be useful in real websites. I think it's secure, but I'm not certain - testing would be very much appreciated. This version only updates the cache if the object we're caching has changed, which wastes less disk space and improves caching in proxies, at the expense of a slower update. http://www.zope.org/Members/itamar/ZCache -- Itamar S.T. itamars@ibm.net
