Hello all,

I am having a problem in using Squid Cache version 2.6.STABLE12 as a
reverse-proxy server for my webserver.
Webserver is running on 192.168.7.1 and squid is running on
192.168.7.3 (public-ip:67.107.xx.xx).

My hosts config. and squid.conf details are below.
First problem is when I start the squid I gets the warning about the
'localhost' as a name server, but squid starts okay and start serving
the requests.
Second problem is over a period of time I gets 'WARNING: Forwarding
loop detected for:' entry in cache.log
which causes to squid to stop working and I have to restart the squid
to make it operational.

Can you please tell me what I'm missing here. Thanks for reading such
long loglines.

Regards,
Suhaib.
