When a user accesses an original server using a user PC (12), a router in a center (4) receives a user access request, and transmits it to a reception and authentication server (2), and inquires of a CDN management server (1) whether or not the request can be accepted. When the CDN management server (1) determines that the user access request can be accepted, it detects a splitter/cache server (8) geographically closest to the user PC (12), and passes a one-time password to the splitter/cache server. The user PC (12) uses the one-time password to access the splitter/cache server (8), and successfully accesses the target contents.
