# 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.
class NullStore < Store
