Re: [squid-users] R: [squid-users] Connection to webmail sites problem using more than one parent proxy

Hi Amos!

I have tried, to disable the ICP queries with the option "no-query"
and the configuration look like that:

cache_peer myparentproxy1.dipvvf.it parent 3128 3130 sourcehash
round-robin no-query

cache_peer myparentproxy2.dipvvf.it parent 3128 3130 sourcehash
round-robin no-query

cache_peer myparentproxy3.dipvvf.it parent 3128 3130 no-query
round-robin sourcehash

It seems to work , but the connection are established only on one
parentproxy, even if the clients ip addresses are different.

What's wrong?

Can u tellme where can I found some good example of configuration
related to my problem?

Thank you once a time!

Sergio
