propably this just happened when pasting into the email, but just in case, in both urls in your sample scripts the ":" were missing (after "http").
when opening those (fixed) URLs with MU Xtra and my little HTTP Sniffer (http://dasdeck.de/staff/valentin/lingo/http_class/http_class_v1.1.zip; really a handy tool :-), I can see in the response headers that this web server uses some tool called "Redline Networks Web I/O Processor" (http://www.juniper.net/company/presscenter/pr/2003/rl/pr-030918.html).
Maybe there is some incompatibility between this tool and lingo's built-in network comands? I have no problems opening those URLs with MU Xtra, though.
