(PowerBuilder) HTTPS Windows Integrated Authentication

This example pertains to running on the Windows operating system only.

It provides guidance on how to send HTTP requests using the current logged-on Windows user credentials. This is where NTLM/Negotiate authentication is used, but the login/password credentials are not explicitly provided by the application, but are implicitly provided based on the Windows logged-on user (i.e. the Windows account for the running process).

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// Chilkat implements the NTLM protocol directly, which is how it can be used on non-Windows systems.
// However, Chilkat can also optionally use Microsoft's SSPI (see https://docs.microsoft.com/en-us/windows/desktop/secauthn/ssp-packages-provided-by-microsoft) 
// to allow for Windows Integrated Authentication.

// Setting the HTTP Login equal to the empty string, and the Password equal to the keyword "default"
// will cause Chilkat to use the Microsoft SSPI w/ integrated authentication.

// Automatically follow redirects.

// then make sure Chilkat both saves and sends cookies:
