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

//  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.

//  See this example for details on
//  how to get (and cache) a form digest value

//  Add additional required headers.
