Well, "the" proxy is anything between galeon and the web server :-)

Hmm, yeah, what I was asking was, how can I send packets through the
proxy and see what is happening? Of course I've already done traceroute,
tcptraceroute and an etherreal capture, none of which told me anything I
didn't already know, that is, one of the items in the proxy chain is
broken.

Of course, since this email was sent, I phoned the BOC again, only to be
told that this time, others were seeing the same problem - heh, I just
reported it first :-)
