Hello All,
We have three squid servers for testing and for our requirement we
configured as follows,
squid1.conf
cache_peer squid2 sibling 80 3130
squid2.conf
cache_peer squid3 sibling 80 3130 allow-miss
We are getting the following error "Valid document was not found in
the cache and 'only-if-cached' directive was specified", When
squid1 makes request to squid2 and in turn squid2 makes request to
squid3
Which squid version?
The setup works fine when we use allow-miss option. We may include few
other squid servers as sibling in future. In this case allow-miss tag
will cause any forwarding loop?
Yes it will.
or it causes any trouble?
You trade only-if-cached messages, for forwarding-loop errors or "slow"
requests looping around consuming resources at multiple peers.
Can any one explain how allow-miss?
In the configuration above it permits squid2 to send a request through
squid3 even if squid2 was informed (via ICP MISS) that it did not exist
there.
squid1 adds the only-if-cached to prevent looping, but squid2 ignores
that. Somehow it advertised to squid1 that it had the object when it did
not, its not clear why.
