// 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"

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

// If SharePoint Windows classic authentication is used, then set the 
// Login, Password, LoginDomain, and NtlmAuth properties.
http.Login = "SHAREPOINT_USERNAME";
http.Password = "SHAREPOINT_PASSWORD";
http.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
