They don't have 'em.

Digests are usable.

I've checked this first and all seem to be ok!

Another question: when I have one or more parents I get peer digest
state `Forbidden' for them all. Ex.:
  cache_peer proxy.ukrsat.com parent 3128 3130
  cache_peer sv.us.ircache.net sibling 3128 3130
And when all of my peers are siblings I get `success'. Ex.:
  cache_peer proxy.ukrsat.com sibling 3128 3130
  cache_peer sv.us.ircache.net sibling 3128 3130
Why is that?
