username/password dialog produced by browser instead of proxied content

[GoogleCodeExporter]

I don't seem to be able to get your version 0.4 of the reverse proxy to 
work. I run a win2k3 server with all latest patches applied, and what 
happens when I follow the readme instructions is I get a username/password 
dialog on trying to connect with the web browser to the URL which should be 
delivering content of the proxied site.

Am I not understanding something properly here? The server is running IIS 
on port 80 as well as a turbogears app on port 8001. I've followed the 
readme in an attempt at setting up http://mysite/TGApp to deliver the 
turbogears site from port 8001. The web.config file thus contains this:
<add key="proxyUrl" value="http://localhost:8001" />

Adding traceRedirect also appears to have no effect, nothing gets written 
to the application log.
