Caching in Zend Framework is operated by frontends while cache records are stored through backend adapters (File, Sqlite,Memcache…) through a flexible system of IDs and tags. Using those, it is easy to delete specific types of records afterwards (for example: “delete all cache records marked with a given tag”).
The core of the module (Zend_Cache_Core) is generic, flexible and configurable. Yet, for your specific needs there are cache frontends that extend Zend_Cache_Core for convenience: Output, File, Function and Class.
