PROBLEM TO BE SOLVED: To provide an information processing method by which an ISP or the like can surely inform a user being under contract of information. SOLUTION: At the time of initial access of a user terminal 1, an RADIUS server 3 outputs the IP address of the user terminal 1 to an access DB server 4 posterior to user authentication. The access DB server 4 registers the IP address in an inside DB. Then, a Web server 5 redirects an 'notification page' carrying contents of which a system 2 should notify the user terminal 1 in response to an instruction from the access DB server 4. Afterwards, a page requested by a user is displayed. When the URL of the 'notification page' is designated, and the IP address of the user terminal 1 is registered in the DB of the access DB server 4, the 'notification page' display is not operated. When the user performs line disconnection, the access DB server 4 erases the registration of the IP address of the user terminal 1. |
