    // 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.

    // ----------------------------------------------------------------------------------------------
    // The code above this comment could be placed inside a function/subroutine within the application
    // because the connection does not need to be made for every request.  Once the connection is made
    // the app may send many requests..
    // ----------------------------------------------------------------------------------------------

    // Let's load a previously computed SAS token and use it.
    // See Azure Shared Access Signature for an example to genenerate an Azure SAS token.
    sbToken := chilkat.NewStringBuilder()

    // Standard brokered message properties are placed in a BrokerProperties HTTP header. 
    // The broker properties must be serialized in JSON format. To specify a TimeToLive value of 3600 seconds 
    // and to add a message label "M1" to the message..
