Re: [squid-users] Round robin upstream parents....

You need to use the cache-peer option in the squid configuration file:

For example:

        cache_peer proxy.parent.com parent 3128 3130 round-robin
        cache_peer proxy.parent2.com parent 3128 3130 round-robin

If one goes down, it will be marked as 'invalid' and will not be used
untill it's available again.
But pls note that round robin proxies can give problems with 'shopping
sites' or similar. -something I discovered a few weeks ago.
because most sites are 'storing' the IP, and because the ip can change,
some big problems can occurs. (you can solve this for particular
websites by using cache_peer_access option but then you won't have
'round robin' for those websites)

The ip address of your local proxy or the parent proxy? The IP visible
to the outside world is the 'highest" proxy. So the one that is
connect to the internet.
