Message Excerpt

Unfortunately Alan, the flag would only help REWIND (if there's a fragmented cache) for the first object. Again it's not expensive to add, but you still need a plan to handle the rest of the gaps.

Plain-Text Body

Unfortunately Alan, the flag would only help REWIND (if there's a fragmented cache) for the first object. Again it's not expensive to add, but you still need a plan to handle the rest of the gaps.

IMO, it would be nice to have a counter that increments by 1 for each object in a sub-group. 0 would be the same as FIRST_OBJECT. Then a relay could determine if its cache has holes on a sub-group basis.
