If set to true the controller will throw an InvalidOperationException when a caching attempt is made for a cache which isn't registered. If false (default), the caching attempt for a cache which doesn't exist will result in a no-op. Set to true during testing/debug to see whether you're trying to cache data in non-existing caches.
