Abstract
When a user accesses an original server using a user PC, a router in a center receives a user access request, and transmits it to a reception and authentication server, and inquires of a CDN management server 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 geographically closest to the user PC, and passes a one-time password to the splitter/cache server. The user PC uses the one-time password to access the splitter/cache server, and successfully accesses the target contents.
