Hi:

I have a problem:

I am developing a application that use web service from a web server in Internet. When user's internet port has firewall/proxy authentication things, my app cannot pass it and go to Internet. How can I make it work?

Many Thanks,

Dennis
 
Look into the System.Net.WebProxy. Of course, if the "firewall/proxy authentication things" are configured to block it, then you can't do much (that's their purpose!).

Thanks, Mike.

Is it possible to detect proxy server address and port on the run time? So I don't need to ask users to enter proxy server information because most of them just don't know.

Thanks,

Dennis

Thanks, Roy. In the following codes from your web page, why do you need
myCache? What does "Negotiate" mean here?

========

private static void SetCredentials(WebProxy proxy,string user,string
password,string domain,string uri)
{

CredentialCache myCache = new CredentialCache();

NetworkCredential myCred =null;



if(domain==null || domain.Length==0)

{ myCred = new NetworkCredential(user,password);}

else

{myCred = new NetworkCredential(user,password,domain);}



myCache.Add(new Uri(uri), "Negotiate", myCred);

proxy.Credentials = myCred;

}



=====

Thanks,



Dennis

I had the same problem, so I wrote a helper class that helps you do
exactly that.
Yes, it uses the WebProxy class, but it makes the process easier.
check it out here.

I was under the impression that that class could grab the settings from the local computer's Internet Settings. I haven't used it, so poke around there?

You need the CredentialCache object for the proxy to work with.
Negotiate means that when the web request will get to the proxy
server, it will "negotiate" with it, meaning "Interact" with it, so it
will answer it for user/password when asked for.
Lookup WebProxy in MSDN...
