Connection ID
Clients are identified by a unique connection ID that exists for the
duration of the connection and is not reused. This connection ID is encoded into the
DriverControl metadata with the key CONNID
. This field is set based on
the client for all inbound messages.
Reply-type messages automatically get the CONNID
of the original outbound message. You can also set the CONNID
using UPoCs. If the CONNID
for an outbound message is not valid, then the message fails
sending and transitions to the error database or send fail procedure.
