[zeromq-dev] Friendly IDs

[Roberto Ostinelli]

Hello 0mq'ers!
I'm investigating 0MQ and up until know I'm enjoying what I'm seeing.

As an academical exercise, I'm trying to understand how to build a simple server that can route a REQ to a very specific Socket based on a "friendly name", and receive a RES from it.

For instance, let's say I have two clients, "Tom" and "Jerry", that somehow authenticate on a server.
I want to be able to have Tom send a REQ specifically to "Jerry", and receive a RES, via a server (i.e. not by a direct connection).

I've seen the examples on how to create a QUEUE device to route XREQ and XRES, however in these examples there are clients on one side and servers on the other, and when a client sends a request, any server on the other side can provide the response. I'd like to have a way for the client "Tom" to specify that it wants its response from the server "Jerry".

Can a kind soul point me in the right direction?

Thank you in advance.
