Re: [squid-users] How do I configure Squid forward all requests to another proxy?

Hi Henrik,

As you mentioned I am following the 2.6 instruction on how to forward request to another proxy.Below is the procedure.

1. cache_peer xxx.xxx.193.87 parent 8080 0 no-query default
2. acl all src 0.0.0.0/0.0.0.0
3. http_access allow all
4. never_direct allow all

Below is the cache.log when I start browsing the web:

[root_at_core2proxy ~]# squid -k reconfigure
[root_at_core2proxy ~]# tail -f /var/log/squid/cache.log
2008/08/21 12:11:20| never_direct = 1
2008/08/21 12:11:20| timedout = 0

It's identical in 2.7.

cache_peer to tell Squid where it may forward.

never_direct to tell squid that it may not go direct.

What does cache.log say on the first request after a restart?
