ZCache 0.4 is incompatible with previous versions - you'll have to recreate all your old ZCache instances. As of version 0.4 ZCache only supports Unix since it uses fcntl.flock for file locking. Patches to add Win32 file locking are welcome. Install ZCache by unpacking the tgz in your Zope folder and making sure you have a folder called "ZCache" (without quotes) folder in var/. http://www.zope.org/Members/itamar/ZCache **New in 0.4:** - The cache is stored in the filesystem (in var/ZCache) instead of in the ZODB. - ZCache generates Expires, Etag for HTTP caching. Last-Modified headers now behaves correctly (on Unix at least). - The cached method is looked up using its absolute path, e.g. /QuickStart/index_html or /Folder/Another Folder/cacheme. -- Itamar S.T. itamars@ibm.net
