[rabbitmq-discuss] Fwd: a few json rpc questions

[mysurf mail]

hi,
Not fully understanding yet.
You wrote :

The RPC servers that serve requests for different applications must be
listening on different work queues. You must ensure that RPC clients use
a routing key that matches the server queue and are different for each
application.

and also you wrote in the last mail that I  Wouldn't need to give each one a
different routing key ( not specifically to support multiple clients in
answer to my second question.

So, in brief. Should i give the same routing key or shouldnt i?
can each application run with the same routing key and queue and all get
their own answer?
Can you elaborate on working with multiple client and rpc ?

Thank you.
