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

    http := chilkat.NewHttp()

    // If SharePoint Windows classic authentication is used, then set the 
    // Login, Password, LoginDomain, and NtlmAuth properties.
    http.SetLogin("SHAREPOINT_USERNAME")
    http.SetPassword("SHAREPOINT_PASSWORD")
    http.SetLoginDomain("SHAREPOINT_NTLM_DOMAIN")
    http.SetNtlmAuth(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.SetAccept("application/json;odata=verbose")

    // Note: The file is not loaded into memory at this point.  It is never fully loaded

    // when the upload occurs.
