The application (to which I have no debug control) reports a failed
internet connection whilst trying to retreive data from an http server.

The line from the config file is:-
cache_peer proxy.easynet.net parent 3128 0

I have no access to the logs from the upstream proxy, so can't tell what
goes to it. As far as I can tell, my proxy is not reporting any
failures.

The only other thing I could do is provide a tcpdump of the traffic to
each of the proxies. Is there a log setting in squid that will show
failed connections?
