Re: [squid-users] cache digest in stead of ICP within my hierarchy ?!?!?

The use of cache digests is selected per peer relation. There is no need
to reconfigure siblings unless you want these to be using your cache
digests rather than or in addition to ICP.

Both peers in the digest relation obviously needs to have support for
cache digests enabled.

If you want to maximise the benefit of cache digests in peering response
time then also use the no-query option. If you don't then cache digests
will only be used if there is a cache hit in a digest, and ICP will still
be used for all other misses.
