Question

I am using this to download html content from a site published on IIS:

using (var client = new WebClient())
{
   client.Credentials =  CredentialCache.DefaultCredentials;
   string html = client.DownloadString("http://site.com");
}

But when the IIS is set to Basic Authentication this doesn’t works. The user already type user and password on the IIS dialog box.

There is a way to make this work without pass a user and password again?

Searching more, I found this:

HttpApplication context = (HttpApplication)HttpContext.Current.ApplicationInstance;
            string authHeader = context.Request.Headers["Authorization"];
            string userNameAndPassword = Encoding.Default.GetString(
                       Convert.FromBase64String(authHeader.Substring(6)));
            string[] parts = userNameAndPassword.Split(':');

            Response.Write(userNameAndPassword);

We can get user and password when the IIS is set do basic authentication!
