Method and system for efficiently storing web pages for quick downloading at a remote device

Abstract

A web server for efficiently storing web pages for quick downloading at a remote device comprises a fast memory, a disk memory and a storage device. The fast memory stores a first plurality of web pages and receives a first signal from the remote device indicating selection of one of the first plurality of web pages. The disk memory stores a second plurality of web pages linked to the first plurality of web pages and transfers all of the second plurality of web pages that are linked to the selected one of the first plurality of web pages to the fast memory in response to the first signal. The disk memory also transmits a second signal to the storage device in response to the first signal. The storage device stores a third plurality of web pages linked to the first plurality of web pages and transfers all of the third plurality of web pages that are linked to the selected ones of the second plurality of web pages to the disk memory in response to the second signal. In addition, the fast memory deletes each of the non-selected first plurality of web pages in response to the first signal so as to allow for memory reuse and to aid in quickly downloading selected web pages to the remote device.
