Hi, thanx for the reply.

I am using oscache and set the "cayenne.default.refresh =3D 20" but
queries seem to be cached longer that 20 sec. I do not explicitly set
the cache group form my queries, do I need to do that or do they end
up in some default group?

Regards,
Atli P=E1ll Hafsteinsson

nd a refetch would update the object cache as a side effect. Personally wit=
h query cache I barely ever look back at the object cache.
