Abstract:
PROBLEM TO BE SOLVED: To provide a data provision system which can perform service provision with high versatility and reduce traffic.SOLUTION: A static download instruction part of a look-ahead update confirmation server periodically sends a download request to a Web server and periodically updates Web page data and a second identifier in a user information storage part. At a time of the download request from a terminal, a difference data transmission part downloads only Web page data which corresponds to the second identifier if a first identifier is different from the second identifier, to the terminal. The terminal pairs the downloaded second identifier with the Web page data as the first identifier and stores them. The first identifier is included in a download request signal transmitted to the look-ahead update confirmation server.
