Version 2.2 of the popular open-source J2EE cache was released on 6th November 2005. Besides bugs being fixed, major improvements have been made to the CacheFilter in many ways:

• Default initialization of the last modified header which reduces transaction overhead and server load
• Preserving more http headers, e.g. the expires header
• Special handling for fragments of a page
• Custom cache key generation by subclassing CacheFilter or by implementing a special interface
• Custom cache groups generation by subclassing CacheFilter or by implementing a special interface
• Support of GZip filters in the filter chain
• Avoids session creation for application scope pages
• Multiple matching cache filters won't dead-lock the response anymore
• The cache won't be serve the same response twice before the client begins to cache it anymore

Furthermore

• Continuous Integration and Dependency Management with Ivy
• Update to JGroups 2.2.8

This release can be downloaded now.
