Abstract
Contents on a server that need not be updated for a fixed period of time are recorded directly in a medium, and desired contents in a local device can be accessed by the same operation procedure as that for accessing the server storing the contents. When a request to acquire delivery information is made from information browsing unit with respect to a local proxy server, the local proxy server analyzes the request, and acquires a server-side control file managed by a server with respect to which the request has been made, and a local-side control file in duplicate information storing unit. If corresponding information exists in the duplicate information storing means and also if the information has the latest version number, the information is fetched from the duplicate information storing unit; otherwise the delivery information is fetched from a server computer.
