Re: cache-peer and hosts file

Good good... We are already serving almost 80% of our content with
squid, so I guess we're doing something right ;)

One last question, on both machines (10.0.0.2 and 10.0.0.3) do I need
to include an entry to the hosts file responding for the main domain?

Someting like this

127.0.0.1	localhost
10.0.0.2	www.example.com

Tnx again
