Udayanga, may I know some usecases for this cache implementation?? Synapse is not designed for the users to interact with the API directly. It has a configuration language to access the API (in most of the cases, apart from the Class mediator and so forth, and the class mediator has to be your last option).
Can you explain how this cache is being used by the configuration language?
