As a last ditch, you might want to think about a server side change to
machine.config. If you cannot make your server side code use an .NET
service proxy to access your service, then this is another way to go.There
are some other threads on this board that relate to proxy, and one of them
links to an article that shows how to make every HTTP request originating
in the server (asp.net wise) use a proxy server.

Dan

Hi
Sorry, I should have made this clearer. I am dealing with an ASP.NET
webforms application and not a WebService.
I know that the WebService class has a Proxy property.
In my case, I am trying to ensure that every request to the web application
is routed via a proxy server URL.
I know that the HttpWebRequest class has a Proxy property as well but I do
not know how to use it. My thinking has been to try and intercept each
request within an HttpModule, but at that point I am stuck.
Thanks
