Manik Surtani commented on JBCACHE-131:
---------------------------------------

The new SingletonCacheLoader delegate should take care of this now.

> Given the following single, unshared cache loader use case in the TreeCache documentation:
> "This is a similar case as the previous one, but here only one node in the cluster interacts with a backend store via its CacheLoader. All other nodes perform in-memory replication. A use case for this is HTTP session replication, where all nodes replicate sessions in-memory, and - in addition - one node saves the sessions to a persistent backend store"
> A cache with attached cache loader should persist the transient state of the cache to disk upon startup in order to maintain cache recoverability.
> I have modified TreeCache to handle this situation, and I will attach the modified code to this issue.
