1.3.2 Client Role
The client is responsible for recording method calls, packaging them up into a COMQC message, and transmitting the message to the message queuing infrastructure.
A COMQC client queues calls to a single COMQC server object, and hence connects to a single message queue. A higher-layer application protocol can maintain multiple COMQC clients that queue calls to different server objects but, for the purpose of this specification, they are independent clients unrelated to each other. That is, even if a client application uses COMQC to queue calls to multiple server objects in the same COM+ application (and hence to the same message queue and the same COMQC server), this involves a separate conceptual COMQC client per server object.
