Release Notes

CacheFu speeds up plone sites transparently using a combination of memory, proxy, and browser caching. CacheFu can be used by itself or with squid and/or apache. CacheFu generates configuration files for squid or squid behind apache (if you are using apache by itself, no special configuration is needed).

Once you have installed CacheFu, your site should run much faster (~10x faster by itself, ~50x faster with squid).

Installing CacheFu

If you're new to CacheFu:

• Copy CacheSetup, PageCacheManager, PolicyHTTPCacheManager, CMFSquidTool to your Products directory
• Restart Zope
• Install the CacheSetup product in the quickinstaller
• Configure using the configlet
• Be sure to read the README.txt about setting up squid

If you're upgrading from 1.0 or 1.0.1 and wish to retain the current configuration:

• Copy CacheSetup, PageCacheManager, PolicyHTTPCacheManager, CMFSquidTool to your Products directory
• Restart Zope
• Click on the reinstall link next to the CacheSetup product in the quickinstaller.
  
• Configure using the configlet

If you're upgrading from an older version or wish to start with a fresh default configuration:

• Uninstall your existing CacheFu via the quickinstaller
  
• Copy CacheSetup, PageCacheManager, PolicyHTTPCacheManager, CMFSquidTool to your Products directory
• Restart Zope
• Install the CacheSetup product in the quickinstaller
• Configure using the configlet
• Be sure to read the README.txt about setting up squid

Using Squid

Change the settings in squid/squid.cfg to reflect your system. Run squid/makeconfig to generate your squid/apache files. Run the generated deploy script to deploy the squid configuration files. If you are using squid behind apache, incorporate the generated httpd.conf into your own apache httpd.conf file

Feature enhancements in this release
