Detailed Description

A cache caching cached values.

This may sound very silly, but this class is reponsible for caching values that are retrieved from other caches. But this actually makes sense when caching large objects, since most cache implementations serialize and deserialze the cached values, leading to multiple instantiations of the cached objects. This inner cache makes sure that the objects don't get unserialized multiple times, which can have serious impact on performance and/or memory usage and/or application integrity.
