this is the cache functionality

A cache -- pronounced CASH -- is hardware or software that is used to store something, usually data, temporarily in a computing environment. It is a small amount of faster, more expensive memory used to improve the performance of recently or frequently accessed data.

cache can be saved

1. in memory
2. on disk
3. in database

You must enable or simulate cash functionality.
