Right. A client getting a forwarding denied message is quite a harsh
thing for a false cache digest hit, however we're just going to enable
miss_access for certain siblings and I'll just watch the MISS stats for
them until the recovery code has been done.

A case of A requestes from B, B gives a 403 error on that hit, A should
ignore and fetch directly or from the next sibling if possible. Whatever
the outcome, it's good to see cache-digests :-)
