How to talk to a specific thread in a server

Thank you very much for your reply.
I did what you said, but the behavior is very confusing.
I create two channels in lua script, and correspond each channel to a pair
of client and server threads.
In the server side, each thread registers its own server obj to its
own Registry_server, and of course they have different dispatch functions.
Now the result is only one server thread receive all requests from client,
and it selects different dispatch function to run based on the request.
But I want different threads to run different dispatch function, not only
one server thread process all requests using different dispatch functions.
Do you have any ideas about this?
