Thank you very much Henrik for your reply!
Everything is working. :)
A piece of my logfile for others:
1268176051.830 7 10.95.4.46 TCP_MISS/200 1315 GET
http://www.the-west.gr/images/index/mini.png - CD_SIBLING_HIT/10.95.4.50

By the way, the load balancing method I am using is "Observed member"
(on option of my load balancer) and I have to say that it works just great.
Thanks again!

Hi,
I'm having some difficulty trying to set up my squid servers to use
cache-digests.
Should be automatic unless you explicitly disable it.
First of all, in order to use cache-digests, must I also use ICP?
No.
I do not get any errors, but I do not know even if it's working. What
should I see in the access.log?
CD_PARENT_HIT / CD_SIBLING_HIT on parent/sibling cache hits.
My setup is made up of 3 servers(squid on all 3) behind a load balancer
on the same subnet.
What load balancing method are you using?
The only thing I can get from squid's logs is (from server-squid1 access
log file):
TCP_MEM_HIT/200 2366753 GET
http://server-squid2:3128/squid-internal-periodic/store_digest - NONE/-
application/cache-digest
Thats the digest exchange.
From what I can understand, my server fetches the cache digest. But
what happens from there on? What happens if the requested site is found
on my sibling's cache? How does squid request it from the sibling cache,
and what is seen, if anything, in the logfile?
It requests the objects using HTTP just as any other client.
But a request only takes place if the requested object is not in the
local cache but the peers cache digest indicates it's available there.
additionally the request must not match hierarchy_stoplist or any cache
deny rules, or Squid won't consider using a sibling for the request.

Henrik
