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

' Note: The application does not need to explicitly set the following
' headers: x-ms-date, Authorization.  These headers
' are automatically set by Chilkat.

' with an XML response body.
