A port listening service operating in at system level is assigned to listen on a static port. The static port can index a plurality of unique IDs associated with a plurality of applications operating in a session level. The server application can then provide to a client the unique connection ID, the IP address of the server, and the static port number for a connection. If the client connects by referencing the unique connection ID, the port listening service can forward a corresponding socket for the connection to the appropriate application instance, such that the application still operates in a session level. As such, the port listening service can dispatch connection services for a single static port to multiple different application instances running in a session level.
