Release Notes - Release Candidate

(18th September 2005 - by Lars Torunski)

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
• Support of GZip filters in the filter chain
• Custom key generation by subclassing CacheFilter or by implementing a special interface
• Preserving more http headers, e.g. the expires header
• Special handling for fragments of a page
• Avoids session creation for application scope pages
• Multiple matching cache filters won't dead-lock the response anymore
