HTTP Negotiate/ Kerberos Authentication

To use Kerberos HTTP authentication, simply set the Login, Password, LoginDomain, and NegotiateAuth properties prior to calling any HTTP method (such as Download, QuickGetStr, SynchronousRequest, etc.)

Chilkat.Http http = new Chilkat.Http();

bool success;

//  Any string unlocks the component for the 1st 30-days.
success = http.UnlockComponent("Anything for 30-day trial");
if (success != true) {
    MessageBox.Show(http.LastErrorText);
    return;
}

//  Set the login/password for HTTP NTLM Authentication:
http.Login = "myLogin";
http.Password = "myPassword";
http.LoginDomain = "myLoginDomain";
//  Negotiate authentication allows the HTTP client
//  to dynamically select either Kerberos or NTLM, depending
//  on what the server supports.
http.NegotiateAuth = true;

//  Download a .zip from chilkatsoft.com:
//  PS> This download URL doesn't actually require
//  authentication.  You'll want to replace this URL with your own.
success = http.Download("http://www.chilkatsoft.com/preRelease/ChilkatDotNet2.zip","ChilkatDotNet2.zip");
if (success != true) {
    MessageBox.Show(http.LastErrorText);
}
else {
    MessageBox.Show("Download Complete!");
