PURPOSE: An automatic login system is provided to offer more convenient and stable method to a user, and to give a site provider an opportunity to let more users know a site. CONSTITUTION: If the user logs in to the site of the site provider, a main server program(2100) of the site provider generates sub servers(2110,2120) for respective clients(3110,3120). The sub server uses a thread for an executing capability. The sub server stores the information for a new site transferred from a client(3110) in a database while keeping the connection with the client. A client program receives an execution command from the main server program. The client program residing in a user computer performs login if the information is existed in a cache when the user connects to a constant site. The client program is terminated if the connection with the site provider is cut off. If the client program is terminated, the sub server allotted to the client is terminated too. The client program is terminated after deleting a recording cache used by the user.
