' Login, Password, LoginDomain, and NtlmAuth properties.

' 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


' To create a folder, we're going to POST to

' This example will create a folder named ChilkatTest in /Documents
