| Release Notes(6th August, 2001 - by Todd Gochenour, tgochenour@peregrine.com) 
	Added boolean "cache.memory" attribute to oscache.properties to eliminate memory consumption and rely strictly on disk storage.Added three interfaces "CacheLog", "CacheProperties", and "CacheContents" to allow plugable implementations for these functions. The CacheContents interface allows the pages to be cached using a database.Added "Language" attribute to CacheTag and FlushTag to distinguish a page that supports I18N generation. The ISO-639 language code is used when the scope of the page is "Application". The code defines a subdirectory under the "application" directory of file caching.Modified the CacheAdministrator.generateKey() function to append the request's QueryString to the URI when automatically generating keys. The QueryString is encoded using the MD5 digest base64 algorithms.Added attribute "encoding" to a CacheTag so that the file IO does proper conversion when reading and writing the cache files. (per suggestion of Pedro Gomez)Added retries when SecurityException is thrown. Java has no built in exclusive file locking implementations. The file is written to a lock file and then renamed as an atomic operation so that multiple processes on the same box can reliable access cache data.Added "pattern" attribute to FlushTag which invokes a CacheHashMap.flushPattern() function to scan for and flush all keys that contain the value of the pattern. (per suggestion of Todd Rudrick)Added support for a CacheTag time value of zero which turns off caching for that tag. (per suggestion of Pedro Gomez) |
