> Based on a query in MQTT Google group, a query was posted with a requirement that the server should not publish message to a subscriber if messages are published by the same client-id and subscribed by the using the same client-id for the same topic. In this case a client connection may both publish and subscribe to a topic and the subscriber should inhibit the delivery of messages published by its own connection. This feature is available in JMS and a subscriber can inhibit to receive publication by using the noLocal flag during subscription.
> This feature is also needed to enable bridging and making proxy subscription between servers so as to stop messages going round in loops.
> I would like propose to add a element in SUBSCRIBE Control packet for individual subscriptions to make a choice on noLocal parameter.  This field could be shared in the same byte as for requstedQos.
