' 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"

Dim http As 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"
http.NtlmAuth = True

' -------------------------------------------------------------------------
' 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
' -------------------------------------------------------------------------

' Indicate that we want a JSON reply
http.Accept = "application/json;odata=verbose"
http.AcceptCharset = "utf-8"
