ASP.NET application how to check the proxy used for request?

Question

I've an application that calls some services through a web-proxy. I'd like to show the information about the proxy used for requests. How can I do this?

My code is like the follow:

WebRequest request = WebRequest.Create(url);
request.Credentials = CredentialCache.DefaultCredentials;
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
log(response.StatusDescription);
// HERE I'd like something like log(request.getProxy()))
reponse.Close();

Any idea? Thanks.

Proxy can be configured for the whole application and can be overridden for certain WebRequest. For the application it can be obtained by this code (it looks like it is your case):

IWebProxy appProxy = WebRequest.DefaultWebProxy;

For a certain WebRequest:

IWebProxy requestProxy = request.Proxy;

Then you can log the information from that IWebProxy:

string proxyAddress = appProxy.GetProxy(new Uri(url)).ToString();
Console.WriteLine(proxyaddress);
