Abstract

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.

Claims

1. In a World Wide Web (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 pages respectively designating the URLs of target Web pages, a system for updating said embedded links in source Web pages when the URL of a target Web page is moved comprising:

means associated with the target Web page of a selected link in a requesting Web page for informing the receiving display station of a requesting page that the target page has moved;

means associated with the receiving display station of the requesting page responsive to said informing means for forwarding the URL of the source of the requesting page to the original URL of the target page;

means associated with the original URL of the target page for returning the new URL of the target page to the source of the requesting page; and

means associated with the source of the requesting page for updating said selected link with the new URL of the target page.

2. The system of claim 1 further including means for forwarding the contents of the source Web page of the requesting page along with its URL back to the original target page URL.

3. The system of claim 2 wherein said means for returning the new URL of the target page also updates the selected embedded link in the source Web pace of the requesting page with said new URL.

4. The system of claim 3 wherein said means associated with the target page for said informing is a detour page.

5. The system of claim 4 further including Web browser means associated with said requesting page for accessing Web pages requested by said requesting page said browser including the means for forwarding said source Web page of the requesting page contents and URL to said detour page.

6. The system of claim 3 further including;

security means for limiting access to said source Web page of the requesting page from said target page; and

means for permitting said return of said new target page URL and said updating of said embedded link when said access limitations are met.

7. The system of claim 6:

further including a Web server connecting the display station having the source Web page of the requesting page to the Web, and

wherein said security means for limiting access and said means for permitting access are included in said Web server.

8. In a 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 URLs remote from said stations, said Web pages being linkable with each other through embedded links in source Web pages respectively designating the URLs of target Web pages, a method for updating said embedded links in source Web pages when the URL of a target Web page is moved comprising:

informing the receiving display station of a requesting page through the target page original site that the target page has moved;

forwarding the URL of the source page to the original URL of the target page responsive to said informing step;

returning the new URL of the target page to the source of the requesting page; and

updating said selected link in said source page of the requesting page with the new URL of the target page.

9. The method of claim 8 further including the step of:

forwarding the contents of the source Web page of the requesting page along with its URL back to the original target page URL.

10. The method of claim 9 wherein said step of returning the new URL of the target page also updates the selected embedded link in the source Web page of the requesting page to be updated with said new URL.

11. The method of claim 10 wherein said step of informing from the target page is carried out by setting up a detour page.

12. The method of claim 11 further including a Web browser process associated with said requesting page for accessing Web pages requested by said requesting page, said browser process including the steps of forwarding said source Web page of the requesting page contents and URL to said detour page.

13. The method of claim 10 further including:

the security step of limiting access to said source Web page of said requesting page from said target page; and

permitting said return of said new target page URL and said updating of said embedded link when said access limitations are met.

14. The method of claim 13 wherein the system further includes a Web server connecting the display station having the source Web page of the requesting page to the Web, and

wherein said security steps for limiting access and said steps for permitting access are carried out in said Web server.

15. A computer program having code recorded on a computer readable medium for updating said embedded links in source Web pages when the URL of a target Web page is moved in a 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 URLs remote from said stations, said Web pages being linkable with each other through embedded links in source Web pages respectively designating the URLs of target Web pages comprising:

means associated with the target Web page of a selected link in a requesting Web page for informing the receiving display station of a requesting page that the target page has moved;

means associated with the receiving display station of the requesting page responsive to said informing means for forwarding the URL of the source of the requesting page to the original URL of the target page;

means associated with the original URL of the target page for returning the new URL of the target page to the source of the requesting page; and

means associated with the source of the requesting page for updating said selected link with the new URL of the target page.

16. The computer program of claim 15 further including means for forwarding the contents of the source of the requesting page along with its URL back to the original target page URL.

17. The computer program of claim 16 wherein said means for returning the new URL of the target page also updates the selected embedded link in the source Web page of the requesting page with said new URL.

18. The computer program of claim 17 wherein said means associated with the target page for said informing is a detour page.

19. The computer program of claim 18 further including a Web browser program associated with said requesting page for accessing Web pages requested by said requesting page, said browser including the means for forwarding said source Web page of the requesting page contents and URL to said detour page.

20. The computer program of claim 17 further including:

security means for limiting access to said source web page of the requesting page from said target page; and

means for permitting said return of said new target page URL and said updating of said embedded link when said access limitations are met.

21. The computer program of claim 20:

further including a Web server connecting the display station having the source Web page of the requesting page to the Web, and

wherein said security means for limiting access and said means for permitting access are included in said Web server.
