one to one conversations in qpid

[Kalle Kärkkäinen <ka...@intstream.fi>]

Hi,

I need one-to-one channels for server-to-client updates.

How would I go about this? I've been planning on creating a temporary 
queue in client and sending queue name in login request.

Is there another way?

If your clients that are receiving the reply can disconnect then I
would consider using durable queues so that any response will wait on
the queue for the clients return. Temporary queues will be removed if
the client disconnects.

If you can give us more details on the components you are using. such
as broker and client languages and version, then can help further.

There's an example of this in
qpid/cpp/examples/examples/request-response/

If I understand correctly you want to have a 'server' program that 
connects to an AMQP broker, and 'client' programs that then communicate 
through the broker with the 'server' to exploit whatever service its 
offering. The clients each need to have an individual conversation with 
the service.

If so, then yes, create a temporary queue and then set the reply-to on 
messages sent to the service. That service can then use the address 
given to send responses back to the specific client that needs them.
