Overview

Null Cache Store

A cache store implementation which doesn’t actually store anything. Useful in development and test environments where you don’t want caching turned on but need to go through the caching interface.

This cache does implement the local cache strategy, so values will actually be cached inside blocks that utilize this strategy. See ActiveSupport::Cache::Strategy::LocalCache for more details.
