摘要

Embedded links or hotspots in source Web pages are upgraded to reflect the new Universal Resource Locations (URLs) of moved target Web Pages. In a World Wide Web communication network with user access via a plurality of data processor controlled interactive display stations for displaying Web pages transmitted to receiving display stations from Uniform Resource Locations (URLs) remote from said stations, said Web pages being linkable with each other through embedded links in source Web page, a system is provided for updating said embedded links in source Web pages when the URL of a target Web page is moved. The basic system includes means associated with the target Web page of a selected link in a requesting Web page for informing the requesting page that the target page has moved together with means associated with the requesting page responsive to this informing means for forwarding the URL of the source web page of the requesting page to the original URL of the target page so that the source Web page may be thus upgraded on a one time basis the first time a requesting Web page from this source tries to link to a target page with a new URL.
