        With what proxy? I've already said that squid is not
        an ftp proxy.

        What I was saying here is that the FTP protocol has no
        way of supporting this sort of proxy (proxy get in the
        typical ftp client is something completely different,
        a third party transfer). You need an extended client
        which uses some protocol extension to tell any proxy you
        use what it was trying to connect to, or you need whatever
        intercepts port 21 to insert this information into the
        command stream. (A server can, of course, use the SITE
        command for anything, including specifying the target of
        a proxied request.)

        HTTP proxies do have a mechanism for informing the proxy
        of this information and HTTP/1.1 clients and HTTP/1.1 aware
        clients will use a Host header even on requests that they
        don't expect to be proxied, allowing the proxy to get this
        information even if you intercept port 80 and redirect.
