WCF Custom Http Proxy Authentication

Question

Is it possible to provide WCF with a custom proxy address and custom credentials?

I\'ve found this answer on stackoverflow: How to set proxy with credentials to gen

Answer 1

If you set the WebRequest.DefaultWebProxy property to a new WebProxy with credentials, WCF will use it for all HTTP requests that it makes. (This will affect all HttpWebRequests used by the application unless explicitly overridden).

// get this information from the user / config file / etc.
Uri proxyAddress;
string userName;
string password;

// set this before any web requests or WCF calls
WebRequest.DefaultWebProxy = new WebProxy(proxyAddress)
{
    Credentials = new NetworkCredential(userName, password),
};

My blog post on proxy servers contains further details.

Answer 2

The client credentials you're setting are fine in order to authenticate to your services.
For proxy authentication you need to use HttpTransportSecurity.ProxyCredentials.
