PROBLEM TO BE SOLVED: To judge the validity of a request for the transition of a task screen from plural clients in a task, using a WWW. SOLUTION: When a request is issued from a client, an one-time ID generated by a preliminarily decided rule is embedded with 'hidden' being one of the attributes of the <INPUT> tag of an HTML. This one-time ID is constituted of all alphabets, numbers, and the other special characters valid on a unique WWW as a system, and the ID itself is constituted as the string of meaningless random alphabet, numbers, and the other special characters. Thus, the ID is related with the log-in ID of a client by a task program on a server (and a host), so that it is possible to judge which client and which task screen the communication is operated from. |
