Abstract

A server-based application intercepts an initial request for access to documents which may contain imbedded references to linked information. A request is made from the server to the actual location of the requested document as it is found on a network (e.g. WORLD-WIDE WEB, INTERNET, etc.). The document is retrieved into the server and parsed to discover all imbedded addresses contained therein. The server then replaces each imbedded address with its own address plus the original imbedded address such that all future references to the imbedded information will be supplied by the server. Additional linking information, functions and/or environment escape information may then be prepended and/or postpended to the requested document independently through the server.

Claims

1. A system for processing existing hypertext links in a computerized network comprising:

a server which intercepts a first document request before it reaches said computerized network and generates a second request;

a filter which searches for imbedded strings in a document returned to said server pursuant to said second request;

an address modifying function to operatively connect an address of said server to said imbedded strings;

an appending function to append data to said document;

a transferring function which transmits said document with its appended data and modified imbedded strings to complete said first request, and

wherein said returned document appears to a requester unmodified but retains said appended data.

2. A system for processing existing hypertext links in a computerized network as per claim 1, wherein said network is the INTERNET.

3. A system for processing existing hypertext links in a computerized network as per claim 1, wherein said network is the WORLD-WIDE WEB.

4. A system for processing existing hypertext links in a computerized network as per claim 1, wherein said appended data includes a prepend section before the document and a postpend section after said document.

5. A system for processing existing hypertext links in a computerized network as per claim 1, wherein said appended data may be obtained without requiring additional knowledge from an originating requester.

6. A system for processing existing hypertext links in a computerized network as per claim 1, wherein said server'"'"'s interception of said first request is transparent to both an originator of said first request and the network to which it is associated.

7. An article of manufacture comprising a computer user medium having computer readable program code embodied therein which processes existing hypertext links on a computerized network comprising:

computer readable program code which causes a computer server to intercept a first request for a document before it reaches said computerized network and generates a second request;

computer readable program code which causes said computer server to search for imbedded strings in a document returned to said server pursuant to said second request;

computer readable program code which causes said computer server to replace an address of said imbedded string with an absolute address comprising both the address of said server and said address of said imbedded string;

computer readable program code which causes said computer server to append data to said document;

computer readable program code which causes said computer server to transfer said requested document with its appended data and replaced addresses to complete said first request, and wherein said returned document appears to a requester unmodified but retains the appended data.

8. An article of manufacture comprising a computer user medium having computer readable program code embodied therein which processes existing hypertext links on a computerized network as per claim 7, wherein said network is defined as the INTERNET.

9. An article of manufacture comprising a computer user medium having computer readable program code embodied therein which processes existing hypertext links on a computerized network as per claim 7, wherein said network is defined as the WORLD-WIDE WEB.

10. An article of manufacture comprising a computer user medium having computer readable program code embodied therein which processes existing hypertext links on a computerized network as per claim 7, wherein said appended data includes a prepend section before the document and a postpend section after said document.

11. An article of manufacture comprising a computer user medium having computer readable program code embodied therein which processes existing hypertext links on a computerized network as per claim 7, wherein said appended data may be obtained without requiring additional knowledge from an originator of said requested document.

12. An article of manufacture comprising a computer user medium having computer readable program code embodied therein which processes existing hypertext links on a computerized network as per claim 7, wherein said server'"'"'s interception of said first request is transparent to both an originator of said first request and the network to which it is associated.

13. A computer program product usable with a programmable computer having computer readable program code embodied therein which processes existing hypertext links on a computerized network comprising:

computer readable program code which causes a computer server to intercept a first request for a document located on a distributed computer network before it reaches said network;

computer readable program code which causes said computer server to process said request and direct the requested document to be returned to the server;

computer readable program code which causes said computer server to search said document for imbedded strings;

computer readable program code which causes said computer server to replace an address of said imbedded string with an absolute address comprising both the address of said server and said address of said imbedded string;

computer readable program code which causes said computer server to append data to said document;

computer readable program code which causes said computer server to transfer said requested document with its appended data and replaced addresses to complete said first request, and

wherein said returned document appears to a requester unmodified but retains the appended data.

14. A computer program product usable with a programmable computer having computer readable program code embodied therein which processes existing hypertext links on a computerized network as per claim 13, wherein said network is defined as the INTERNET.

15. A computer program product usable with a programmable computer having computer readable program code embodied therein which processes existing hypertext links on a computerized network as per claim 13, wherein said network is defined as the WORLD-WIDE WEB.

16. A computer program product usable with a programmable computer having computer readable program code embodied therein which processes existing hypertext links on a computerized network as per claim 13, wherein said appended data includes a prepend section before the document and a postpend section after said document.

17. A computer program product usable with a programmable computer having computer readable program code embodied therein which processes existing hypertext links on a computerized network as per claim 13, wherein said appended data may be obtained without requiring additional knowledge from an originator of said requested document.

18. A computer program product usable with a programmable computer having computer readable program code embodied therein which processes existing hypertext links on a computerized network as per claim 13, wherein said server--s interception of said first request is both transparent to an originator of said first request as well as the network to which it is associated.
