; Note: Requires Chilkat v9.5.0.65 or greater.

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

; Make the initial connection.
; A single REST object, once connected, can be used for many Azure Service Bus REST API calls.
; The auto-reconnect indicates that if the already-established HTTPS connection is closed,
; then it will be automatically re-established as needed.
