摘要： A server computer and a client computer determine a method of storing user identification information into a connection request packet therebetween. When establishing a connection with the server computer, the client computer stores its own user identification information in a server application into a connection request packet and transmits it. The server computer extracts the converted user identification information, and refers to a task storage table of the application based on the user identification information, and in the case where the task exists, the server computer transmits a connection request acknowledgement packet and establishes the connection.
