Amos,

I managed to get it working once for one IP sending the request onto my
parent, but when I tried to add another peer cache for the same IP but
different port and also domain I received an error relating to not being
allowed to use the same cache_peer IP address, which is fair enough. I've
added another IP to my ubuntu (eth0:1) and assigned my webservice to run
on that - tested ok directly without squid. However, I must have made a
conf file mistake as now it's not working when I go via squid. My conf is
extremely simple as I just want to concentrate on this..:

==
http_port 192.168.1.100:80
cache_peer 192.168.1.101 parent 8800 0 no-query
cache_peer_domain 192.168.1.101 test.test.com
http_access allow all

==

I have a host entry on my pc for the test.test.com domain.

Going over 80 to test.test.com results in:

Error - requested URL could not be retrieved
Invalid URL
Some aspect of the URL is incorrect etc etc

Any pointers gratefully received..

Thanks

Nick
