in thread Multiple Perl files sharing a single socket - is it possible/sensible?

It is entirely possible for the server side to be ready for multiple client connections. I would guess EMS has no problem if all eight of your client scripts connect to it at once. Is there some order which needs to be enforced on these messages, or are they fine to arrive in any order?

    I amend my statement as far as "all 8 messages at once" since most messages only go one way. Like so:

    • Response message - RECEIVE to SEND task on both sides (ILS and EMS will handle this message - contains code notifying that message was accepted or rejected by socket)
    • Ping message - SEND to RECEIVE task (this acts as the "keep alive" mechanism) Pings are sent from both sides at 40-second intervals.
    • Add message - ILS to EMS only
    • Delete message - ILS to EMS only
    • Return message - ILS to EMS only
    • Request message - ILS to EMS only
    • Status Check message - ILS to EMS only
    • Status message - EMS to ILS only

    As a visual representation, a typical transaction would follow this order:

    ILS EMS --- --- Request --> <-- Response (request accepted/rejected) <-- Status (requested item in available/unavailable) Response -->
