Abstract

See full text

The present invention relates to a cache mechanism of a browser apparatus as a World Wide Web (WWW) client and aims at the improvement of utilization efficiency and the shortening of an information acquisition delay time. A cache is constituted in an HDD or DVD-RAM under the control of a Web cache program. A copy of acquired information is stored in the cache. A directory of the cache is managed by a Web cache management table, and the control is made so that the writing of the cache contents and necessary entries of the management table is completed before the DVD-RAM is removed from the browser apparatus. A browsing work can be continued smoothly by loading the DVD-RAM to another browser apparatus. Also, if an information provider provides information in a form stored in a disk in the form of a Web cache, the browsing of the information becomes possible with the same URL as that in WWW access.
