How to create dynamic FIX sessions using Quick Fix

SessionSettings settings = new SessionSettings();

                SessionID id1 = new SessionID(new BeginString("FIX.4.2"), 
			new SenderCompID("FixServer"), 
			new TargetCompID("Client1"), "Session1");
                Dictionary d = new Dictionary();

                d.setString("ConnectionType", "acceptor");
                d.setLong("SocketAcceptPort", 5001);
                d.setString("FileLogPath", "Log");
                d.setString("StartTime", "00:00:00");
                d.setString("EndTime", "00:00:00");
                d.setString("FileStorePath", @"c:\fixfiles");
                d.setBool("UseDataDictionary", true);
                d.setString("DataDictionary", @"FIX42.xml");

                settings.set(id1,d);

                id1= new SessionID(new BeginString("FIX.4.2"), 
			new SenderCompID("FixServer"), 
			new TargetCompID("Client2"), "Session2");
                d = new Dictionary();

                d.setString("ConnectionType", "acceptor");
                d.setLong("SocketAcceptPort", 5001);
                d.setString("FileLogPath", "Log");
                d.setString("StartTime", "00:00:00");
                d.setString("EndTime", "00:00:00");
                d.setString("FileStorePath", @"c:\fixfiles");
                d.setBool("UseDataDictionary", true);
                d.setString("DataDictionary", @"FIX42.xml");

                settings.set(id1, d);

                                                
                FixServerApplication application = new FixServerApplication();
                FileStoreFactory storeFactory = new FileStoreFactory(settings);
                ScreenLogFactory logFactory = new ScreenLogFactory(settings);
                MessageFactory messageFactory = new DefaultMessageFactory();
                SocketAcceptor acceptor
                  = new SocketAcceptor(application, storeFactory, settings, 
			logFactory, messageFactory);

                acceptor.start();
                Console.WriteLine("press  to quit");
                Console.Read();
                acceptor.stop();
