In grepping through urllib2.py, I see where the ftp code does a lookup, but I don't see where one happens for http. Now, many proxies don't handle http byteranges well (a feature yum uses and a reason we generally recommend ftp behind a proxy) so you may be SOL. If it's a dns problem that's getting you, can you plug in the IP address directly? -Michael -- Michael D.
