> Where Session is NH session, of course. The second level cache is
> configured and turned on. hibernate.cache.use_query_cache is set to
> true. The TDomainObject has caching enabled in the mapping file. When
> I run the program with log level cranked up to DEBUG, I can see NH
> putting data into the cache, and I can see the objects in my second
> level cache (to be specific, I am using NCache -- an out of proc,
> cluster-level cache). The problem is that when the program is run
> repeatedly, it always hits the database, regardless of whether the
> results are already in the cache or not. If I run Session.Load(typeof
> (TDomainObject), 1) when there's something in the cache -- it works as
> expected -- i.e. NH checks the cache, and returns the object out of
> memory.
