Re: transparent proxy & DNS lookups

If netscape is using a proxy server (and it knows it), then it doesn't
do any DNS lookups for browsing - it just palms the URL's off onto the
proxy. If it doesn't think it's using a proxy, then it has to do the DNS
lookups itself, then connects to the appropriate IP number, at which point
your transparent proxy cuts in, and redirects everything. There's not
a lot you can do about that really - if netscape doesn't think it's using
a proxy, then it's got to do the lookup, to figure out where to connect
