Creates an Azure Service Bus Subscription.

Note: This example requires Chilkat v9.5.0.65 or greater.

Perl

use chilkat();

# 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..
