CD_PARENT_HIT is a HIT instead of TCP_HIT. Though it indicates a
cache-digest hit and I don't see digest enabled in your example config.

Note: If you have disabled caching in the frontend like most CARP
configs need you will not see any HIT there as all requests are MISS at
frontend and passed to backend.

The backend logs should still be recording HIT/MISS like normal.
