Accessing a web service - proxy problem

[Jon]

I wrote a VS 2005 C# express programme that accesses a web service. It works fine when there's a
direct connection to the internet, but on two different PCs with internet access via a proxy, I get
this exception:

System.Net.WebE xception: The request failed with HTTP status 407: Proxy Authentication Required.
at System.Web.Serv ices.Protocols. SoapHttpClientP rotocol.ReadRes ponse(SoapClien tMessage message,
WebResponse response, Stream responseStream, Boolean asyncCall)
at System.Web.Serv ices.Protocols. SoapHttpClientP rotocol.Invoke( String methodName, Object[]
parameters)

The internet works fine on this PC with IE and Firefox. In these two browsers, a proxy is set up.
Use a proxy server for your LAN is ticked, and the address and port (80) has been entered.

Am I right in saying that my programme is not able to access the settings of the web browsers, so I
need to configure my programme with the proxy details. If so, how do I supply this information to
the proxy. Or is there a way to access the settings from IE/Firefox?

Thanks for you suggestion - I've re-posted my question there.

hah, interesting timing, I had a very similar issue just the other day,
my workaround was to do this...

WebProxy proxy = new WebProxy(@"http ://proxy.prod.ques t.corp:8080");
proxy.Credentia ls = new NetworkCredenti al(usr, pswd, "prod");
WebRequest.Defa ultWebProxy = proxy;

Cheers Tim.

Oops, I shouldn't really have shown the proxy server address here :-)
oh well.

Also, I call this a workaround, because I think that the more correct
thing to do is for the Soap client to provide a .proxy property so that
it can include the authentication in the soap header (I think this is
correct) as this approach, is a sledgehammer approach...but it does
work, and thats the main thing.

Cheers Tim.

Cool, thanks for that. That link that Steven sent you is useful.
