Abstract: Data for selected web sites likely to be accessed are stored on memory media (compact disks) that are physically transported to subscribers for use when browsing the Internet. New copies of the memory media with the data for the selected web sites are periodically produced and distributed to the subscribers. In addition, if the data cached on the memory media are stored on a local hard drive of the subscriber, the content of the cache can be updated by a local proxy program during the subscriber's connection to the network when the connection is not otherwise in use. The local proxy program is installed on the subscriber's computer from the distributed memory media. A data center provides Intelligent Prefetching and implements a validation service to determine if the cached data items are current. If not, the current data are loaded into the browser program through the Internet connection.
