Abstract

Maintenance of a repository of summary data about documents associated with document locators, the repository of summary data stored separately from the documents and containing the document locators, when a user requests a document associated with one of the document locators, by requesting the document associated with the document locator; receiving a result based on the request; analyzing the result to determine the validity of the document locator; and requesting an update of the repository based on the validity of the document locator. In a network environment, the document locators are uniform resource locators, or URLs. The repository update may for example take the form of deleting the URL from the repository, or moving it to another location for further examination.

Claims

1. A method of maintaining a repository of summary data about documents associated with document locators, the repository of summary data stored separately from the documents and containing the document locators, when a user requests the retrieval of a document associated with one of the document locators, comprising the steps of:

requesting the retrieval of the document associated with the document locator;

receiving a result based upon the request analyzing the result to determine the validity of the document locator; and

requesting an update of the repository based on the validity of the document locator.

2. The method of claim 1 wherein the requesting an update step comprises requesting that the document locator be deleted from the repository.

3. The method of claim 1 wherein the requesting an update step comprises requesting that the document locator be moved from the repository to another location.

4. The method of claim 1 wherein the documents are accessed via a network server.

5. The method of claim 4 wherein the document locator is a uniform resource locator (URL).

6. The method of claim 4 further comprising the step of associating the user request with the user.

7. The method of claim 5 further comprising the step of determining if the request is a URL request.

8. The method of claim 5 wherein the result is a response message received from the server and wherein the step of analyzing the result comprises examining a status line of the response message.

9. The method of claim 5 wherein the URL is invalid.

10. The method of claim 7 wherein the repository update comprises deleting the invalid URL.

11. The method of claim 7 wherein the repository update comprises moving the URL to another location.

12. The method of claim 1 further comprising the step of sending a notification to the user containing the result.

13. The method of claim 12 wherein the notification also comprises an explanation of the result.

14. A system for maintaining a repository of summary data about documents associated with document locators, the repository of summary data stored separately from the documents and containing the document locators, when a user requests the retrieval of a document associated with one of the document locators, the system comprising:

means for requesting the retrieval of the document associated with the document locator;

means for receiving a result based upon the request, the receiving means coupled to the document requesting means;

an analyzer, coupled to the receiving means, for analyzing the result to determine the validity of the document locator; and

a repository manager, coupled to the analyzer, for requesting an update of the repository based on the validity of the document locator.

15. The system of claim 14 wherein the repository update request comprises a request that the document locator be deleted from the repository.

16. The system of claim 14 wherein the repository update request comprises a request that the document locator be moved from the repository to another location.

17. The system of claim 14 wherein the documents are accessed via a network server.

18. The system of claim 14 further comprising a session manager for associating the user request with the user.

19. The system of claim 17 wherein the document locator is a uniform resource locator (URL).

20. The system of claim 19 wherein the result is a response message received from the server and wherein the analyzer has means for examining a status line of the response message.

21. The system of claim 20 wherein the repository manager comprises means for requesting that the URL be deleted from the repository if the URL is invalid.

22. The system of claim 19 wherein the repository manager comprises means for requesting that the URL be moved from the repository to another location if the URL is invalid.

23. The system of claim 14 further comprising means for sending a notification to the user containing the result.

24. The system of claim 23 wherein the notification also comprises an explanation of the result.

25. A program storage device readable by a machine, tangibly embodying a program of instructions executable by the machine to perform the method steps for maintaining a repository of summary data about documents associated with document locators, the repository of summary data stored separately from the documents and containing the document locators, when a user requests the retrieval of a document associated with one of the document locators, said method steps comprising:

requesting the retrieval of the document associated with the document locator;

receiving a result based upon the request

analyzing the result to determine the validity of the document locator; and

requesting an update of the repository based on the validity of the document locator.

26. The device of claim 25 wherein the requesting an update step comprises requesting that the document locator be deleted from the repository.

27. The device of claim 25 wherein the requesting an update step comprises requesting that the document locator be moved from the repository to another location.

28. The device of claim 25 wherein the documents are accessed via a network server.

29. The device of claim 28 wherein the document locator is a uniform resource locator (URL).

30. The device of claim 28 further comprising the step of associating the user request with the user.

31. The device of claim 29 further comprising the step of determining if the request is a URL request.

32. The device of claim 29 wherein the result is a response message received from the server and wherein the step of analyzing the result comprises examining a status line of the response message.

33. The device of claim 29 wherein the URL is invalid.

34. The device of claim 33 wherein the repository update comprises deleting the invalid URL.

35. The device of claim 33 wherein the repository update comprises moving the URL to another location.

36. The device of claim 25 further comprising the step of sending a notification to the user containing the result.

37. The device of claim 36 wherein the notification also comprises an explanation of the result.
