I am attempting to write a small SOAP client script using Ruby 1.8.2
for Windows. The SOAP server will be located on the other side of an
authenticating proxy server. I see there's a #setHttpProxy method
available that I can use to specify the host and the port. Is there a
quick and easy way to set the username and password? I tried using
http://username:password / server.com as the URL but no luck.

Any suggestions?
