    //  The following comments apply to SharePoint Windows classic authentication.
    //  -------------------------------------------------------------------------
    //  For example, imagine our SharePoint endpoint is https://xyzoffice.mycompany.com/
    //  The SHAREPOINT_NTLM_DOMAIN would be "mycompany.com"
    //  The SHAREPOINT_HTTPS_DOMAIN would be "xyzoffice.mycompany.com"
    //  Also, the SHAREPOINT_USERNAME would be just the name, not a full email address.
    //  for example, "chilkat" instead of "chilkat@mycompany.com"

    //  If SharePoint Windows classic authentication is used, then set the
    //  Login, Password, LoginDomain, and NtlmAuth properties.

    http.put_Password("SHAREPOINT_PASSWORD");
    http.put_LoginDomain("SHAREPOINT_NTLM_DOMAIN");

    //  -------------------------------------------------------------------------
    //  The more common case is to use SharePoint Online authentication (via the SPOIDCRL cookie).
    //  If so, do not set Login, Password, LoginDomain, and NtlmAuth, and instead
    //  establish the cookie as shown at SharePoint Online Authentication
