set http [new_CkHttp]

# If SharePoint Windows classic authentication is used, then set the 
# Login, Password, LoginDomain, and NtlmAuth properties.
CkHttp_put_Login $http "SHAREPOINT_USERNAME"
CkHttp_put_Password $http "SHAREPOINT_PASSWORD"
CkHttp_put_LoginDomain $http "SHAREPOINT_NTLM_DOMAIN"
CkHttp_put_NtlmAuth $http 1

# 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

# This example will delete the file named "penguins2.jpg" 
# which is located in the "/Documents" folder.
