RE: [squid-users] Help peering httpd accelerators

Unrelated (I think), but out of curiosity, why are you creating digests if
you are using ICP queries (the two are different peering methods)?

I'm interested in the TIMEOUT issue as well, as a majority (~ 70%) of the
ICP requests between my peers (on the same switch) timeout. *shrug*

It seems that it does work sometimes... as I did see in the access logs a
few:

SIBLING_HIT

But most of the time, it is: TIMEOUT_DIRECT

I tried putting the mcast ttl to 4 instead of 1, but that did not help.

Should I be missing with other timeouts? all the squids are in the same
LAN!!

Thanks a lot.
