Also, does nayone know the HTTP method verb for an HTTP GET for the
webclient.UploadValues method? Or all the legal verbs which do not seem to
be documented in the .NET help? I could only find examples of "POST" and it
is a string rather than an enumeration! What were they thinking??? "GET" and
"HTTPGET" do not work and get complaints as invalid verbs.
