TZP,

Unfortunately I didn't fully understand your question, but I'll try to 
answer it by explaining how the "RTSPServer" code handles RTSP client requests.

The server handles each new client TCP connection (to the RTSP server port 
- e.g., 554) using the routines "RTSPServer::incomingConnectionHandler()" 
and "RTSPServer::incomingConnectionHandler1()".  This calls "accept()" to 
get a new socket just for this client connection.  It then creates a new 
"RTSPClientSession" object to handle incoming requests for this client 
connection.  Note that each "RTSPClientSession" object handles only one 
ongoing client connection.  Note also that the "RTSPServer" object does not 
read any data from a client; it just calls "accept()".  Only the 
"RTSPClientSession" object reads (and handles) data from the client.

If you add
         #define DEBUG 1
to the top of "RTSPServer.cpp", you will see a debugging print out of the 
RTSP server code as it works.
