If i have a valid Dataset or Datatable with rows and i put it into the
cache by way of insert, why would the DS or DT have no rows when i
retrieve it back using get?

Are you sure you''re getting back a DataTable instead of null? It''s possible
that the cache purged the item given the conditions you specified in the
Insert. But if there is a valid DataTable but no rows, then something else
is at work here, not the cache.

Also if you''re using DefaultView you could have problems. If you want to use
dataviews you should create a new DataView when you pull a datatable or
dataset out of the cache.

I use a valid dataset and have tried a datatable, after i retrieve from
the cache, the object is valid( not equal to nothing), but there are no
rows. I guess its a mystery.
