System.Net.CredentialCache supports Digest Auth

In my last post I talked about implementing Digest Authentication in WebAPI. That was a server side implementation, but how do you make requests to that server? Good news: .NET's built in CredentialCache supports Digest Authentication!

PreAuthenticate

Be sure to enable PreAuthenticate, otherwise each request will require a new digest token have to make an additional two requests to get it! Do not worry, the request will not send your credentials without having a token first.

PreAuthenticate = false

PreAuthenticate = true

Test Code

[Fact]

public void DigestCredentials()

{

    var requestUri = new Uri("http://localhost/DigestAuthDemo/");

    var credCache = new CredentialCache

    {

        {

            new Uri("http://localhost/"), 

            "Digest", 

            new NetworkCredential("UserName", "Password", "/")

        }

    };

    using (var clientHander = new HttpClientHandler

    {

        Credentials = credCache,

        PreAuthenticate = true

    })

    using (var httpClient = new HttpClient(clientHander))

    {

        for (var i = 0; i < 5; i++)

        {

            var responseTask = httpClient.GetAsync(requestUri);

            responseTask.Result.EnsureSuccessStatusCode();

        }

    }

}

Enjoy,
