How would I do "Basic Auth"? With a CredentialCache? If I use a
CredentialCache, what do I specify for the uriPrefix argument for the Add
method?

The IT guy at the client side has said that Pocket Internet Explorer
connects without prompting if you put the username and password in the
"Socks 5 Login" settings in the Pocket PC. So apparently it doesn't need a
domain? Do proxy servers require a domain? In Norton's LiveUpdate program,
there is a place to enter a proxy server name, port, user, and password, but
no place for a domain.
