Sorry, I'm missing something really fundamental here...

I apparently don't need to do authentication. (The authentication stuff in
my original example was just copied-and-pasted from the example in the MSDN
docs.) If I remove all references to Credentials, my code still works as
before. As near as I can tell, the minimum code that I need to access a
website in code is:

    ' These two lines are necessary to get through the firewall
    Dim proxy As New WebProxy("<My proxy name:8080>")
    GlobalProxySelection.Select = proxy

    Dim url As String = "<desired website>"
    Dim wr As HttpWebRequest = DirectCast(WebRequest.Create(url),
HttpWebRequest)
    dim response as HttpWebResponse = DirectCast(wr.GetResponse(),
HttpWebResponse)

I just don't want to hard-code my proxy address in my code. But if I remove
the first two code lines, the call to GetResponse fails.

As another attempt to get this to work, I created an app.config file and put
the following into it:

  <?xml version="1.0" encoding="utf-8" ?><configuration>
  <configuration>
    <system.net>
      <defaultProxy>
        <proxy usesystemdefault="true" />
      </defaultProxy>
    </system.net>
  </configuration>

Then I removed the GlobalProxySelection stuff and tried it. Still doesn't
work.
