Abstract

Where a user logs on to a web page server, the server can maintain a history of links to web pages hosted by the server to indicate which links are visited by the user. In consequence, a user may log on to the web page server from any web page-enabled device and the server will be able to differentiate for the user links the user has visited from links that have yet to be visited.

Claims

1. A computer program product in a tangible computer readable storage medium containing instructions which, when performed by a web page server requiring user log-on, causes said server to:

maintain a plurality of history files of said web page indicators on said server, one history file for each of a plurality of users, regardless of the client devices implemented by each of the plurality of users;

responsive to said user requesting a given web page from said server, for each link in said given web page, compare a web page indicator for said each link with web page indicators stored in said history file for said user;

where a first web page indicator for said given web page has been included in at least one of said plurality of history files and content of said given web page is updated by an authorized user, deleting said first web page indicator of said given web page from said at least one of the plurality of history files prior to said plurality of users requesting said given web page in order for said given web page to appear unvisited by any of the plurality of users; and

responsive to a match, modify each said link matched prior to serving up said web page.

2. The computer program product of claim 1 containing instructions which, when performed by said web page server requiring user log-on, further causes said server to:

when said user requests said given web page, update said one history file of said user to include a first web page indicator for said given web page.

3. The computer program product of claim 1 containing instructions which, when performed by said web page server requiring user log-on, further causes said server to:

prior to serving up said given web page, add an indicator to said given web page so that if said given web page is subsequently requested by said user at a client caching of said given web page, said given web page is re-loaded from said server.

4. The computer program product of claim 3 wherein modifying said each link comprises modifying said each link to display in a particular color.

5. The computer program product of claim 3 wherein modifying said each link comprises modifying said link to display in a different font.

6. The computer program product of claim 5 wherein said given web page is coded in hypertext mark-up language (“

html”

), each said web page indicator comprises a universal resource locator (“

URL”

), and modifying said each link comprises adding html code to said each link.

7. A web page server, comprising:

memory storing a user record for each of a plurality of users, each said user record having a history file, regardless of the client devices implemented by each of the plurality of users;

a processor operable to, when a user requests a given web page from said server, for each link in said given web page, compare a web page indicator of said each link with web page indicators stored in said history file for said user;

where a first web page indicator for said given web page has been included in at least one of said plurality of history files and content of said given web page is updated by an authorized user, delete said first web page indicator of said given web page from said at least one of the plurality of history files prior to said plurality of users requesting said given web page in order for said given web page to appear unvisited by any of the plurality of users; and

, on a match, modify said each link prior to serving up said web page.

8. The server of claim 7 wherein said processor is further operable to, when said user requests said given web page, update said history file of said user to include a web page indicator for said given web page.

9. The server of claim 7 wherein said processor is further operable to:

prior to serving up said given web page, add an indicator to said given web page so that if said given web page is subsequently requested by said user at a client caching of said given web page, said given web page is re-loaded from said server.

10. The server of claim 9 wherein said processor is further operable to, when modifying said each link, modifying said each link to display in a particular color.

11. The server of claim 9 wherein said processor is further operable to, when modifying said each link, modifying said each link to display in a different font.

12. The server of claim 11 wherein said given web page is coded in hypertext markup language (“

html”

), each said web page indicator comprises a universal resource locator (“

URL”

), and wherein said processor is operable to, when modifying said each link, modifying said each link by adding html code to said each link.
