Release Notes

CacheFu is a collection of products which aggregate and simplify various caching settings, speeding up Plone sites using a combination of memory, proxy, and browser caching.  CacheFu can be used by itself or with Squid, Varnish, and/or Apache.  Configuration files can be generated for Squid, Varnish, Squid-behind-Apache, Varnish-behind-Apache, and Apache cache proxy (if you are using a non-caching Apache by itself or just Zope-only, no extra configuration files are needed).

CacheFu is currently shipped as a separate add-on to Plone as we expect more releases in the near future to add additional features and flexibility.  CacheFu 1.1.2 has been tested on Plone 3.0 and Plone 2.5+.  For earlier Plone versions, try CacheFu 1.0.3 instead.

New Features in CacheFu 1.1.2

• Improved proxy cache configs for Squid and Varnish.
  
• Some bug fixes.
  

New Features in CacheFu 1.1.1

• New improved proxy cache configs for Squid, Varnish, and Apache (yes, Apache can be used as a proxy cache server -- although it doesn't support PURGE requests).  Look in the 'cachefu-proxy-configs' folder for more information.
  
• Added an VirtualHostMonster 'inside-out' example to the custom rewritePurgeUrls script.  The rewritePurgeUrls script is found in the 'cache_setup' skins folder.
  
• Added support for 'stale-while-revalidate' and 'stale-if-error'.  See http://www.mnot.net/blog/2007/12/12/stale
• Added kss registry to resource cache rule.
  
• Added a cache rule for RSS feeds.
  
• Lots of bug fixes.
  

New Features in CacheFu 1.1

• An "off" switch.  Previously, you had to uninstall in order to turn off caching. Now you can turn it off without losing your configuration.
• Multiple cache policies. A cache policy is a container for cache rules and header-sets so you can now have multiple sets of rules and headers for different occasions or site development purposes.
• Caching of Zope 3 views.
• Customizable purge urls.
• Improved Last-Modified dates.
• Simplified Squid configs.
• Varnish configs.

New CacheFu Manual and Web Caching Reference

A new CacheFu Manual and a Web Caching Reference is nearing completion. Stay tuned for an announcement.

Installing CacheFu

Installing CacheFu for the first time:

1. Copy CacheSetup, PageCacheManager, CMFSquidTool, and PolicyHTTPCacheManager into your Products directory.
2. Restart Zope.
3. Install the CacheFu product via the Plone "Add/Remove Products" page.
4. Optional: Configure via the "Cache Configuration Tool"  (see Configuring CacheFu in the Manual).
5. Optional: Install Squid or Varnish  (see Reverse-Proxy Cache Servers in the Manual).

Upgrading from CacheFu, versions 1.0 - 1.1.1:

1. Copy CacheSetup, PageCacheManager, CMFSquidTool, and PolicyHTTPCacheManager into your Products directory.
2. Restart Zope.
3. Click on the reinstall link next to the CacheSetup product in the Plone "Add/Remove Products" page.

Change log

CacheFu 1.1.2

• Release manager: Ricardo Newbery, ric@digitalmarbles.com.  Compatible with: Plone 3.0 and Plone 2.5+
• Removed some deprecated tests.  [newbery]
• Synced up the squid and varnish configs with the changes in plone.recipe.squid and plone.recipe.varnish.  Mostly removed the special handling of cookie-authenticated requests and in the varnish case, added some handling of cache-control tokens.  [newbery]
• Added a default_ttl of zero seconds to the varnish runner.  [newbery]
• Unauthorized requests now do not trigger a full CacheFu disable. CacheFu is still disabled but no objects are actually removed. A temporary fix for http://plone.org/products/cachefu/issues/134  [newbery]
• Removed no-cache from the default cache policies and added a warning to the noCache and noStore fields about the IE/SSL bug. Fixes http://plone.org/products/cachefu/issues/117  [newbery]
• Fixed reordering UI.  http://plone.org/products/cachefu/issues/131  [newbery]
• Removed lazy expression cleanup routine since we don't do macro caching anymore.  [newbery]
• Fixed UnicodeDecodeError in PT_pt_render().  http://plone.org/products/cachefu/issues/126  [newbery]
• Fixed rewritePurgeUrls.py.  Was referencing the method before its definition.  [newbery]
• Cleaned up the descriptions of some cache rules. [newbery]
• Removed RSS from the container rule since we do this in a separate rule now.  [newbery]
• Fixed typo in getHeaderSetIdForCSSAndJs.py which would throw an error if still using the old cache policy (pre-1.1.1).  [newbery]
