When a plurality of user terminals request a plurality of contents, the numbers of user terminals which request the content are managed. For each of the plurality of contents, the number of content servers which provide that content is decided using the managed numbers. For each of the plurality of contents, the content is installed in content servers as many as the number decided in association with that content, and user terminals which request the content are permitted to access the content servers which provide the content. |
