摘要： PROBLEM TO BE SOLVED: To discriminate users who are accessing a WWW server to comprehend the number of users at all times and to attain simultaneous accesses of users via a single ID by setting accounts of fees for each Web page and storing the total amount of fees.
SOLUTION: A WWW server is set to previously registered IDs and to authenticate the Web page when it is requested by the IDs. The numbers of IDs and licenses which are registered in the WWW server are set to a connection information management DB 106. When a communication controller 102 receives the request information on Web pages from a browser, an ID/connection information acquiring device 103 takes the ID/connection information out of the request information. If the connection is permitted to the WWW server, the controller 102 transfers the request information to the WWW server and acquires the returned response information. The response information includes a character string set part called an HTTP header, in which the response messages of the WWW server, the information on Web pages, etc., are described.
