Abstract

Apparatus and method which allows a user to dynamically gather Web Site status information from a Web Browser. In a preferred embodiment, the present invention allows a user to gather information on which Web Pages within a Web Site have been recently updated. The present invention utilizes a workstation-based custom gateway to interconnect a user'"'"'s Web Browser to the Web Server which hosts the Web Site. This gateway includes a program which receives a user-tailorable search request from a Web Browser, traverses a portion of the Web-accessible file structure of the Web Server, identifies Web Site files which meet the search request criteria, builds a table of results from the search, and returns the search results to the Web Browser. The present invention also allows an administrator to customize the table of results returned to the Web Browser.

12. A computing environment according to claim 11 wherein said searching means executes on a workstation platform.

13. A computing environment according to claim 10 wherein said Web Site has at least one Web Page file.

14. A computing environment according to claim 13 wherein said Web Page files are organized in a hierarchical, web-accessible data structure.

15. A computing environment according to claim 14 wherein said searching means determines which said Web Pages files residing within a user-specified Web Site location have been updated since a user-specified relative date, wherein said user-specified Web Site location and said user-specified relative date are provided to said searching means by said request from said Web Browser.

16. A computing environment according to claim 15 wherein said searching means is restricted to search only said Web Page files which satisfy an administrator-specified file extension restriction, wherein said administrator-specified file extension restriction is provided to said searching means by a prior administrative action.

17. A computing environment according to claim 15 wherein said searching means is restricted to search only said Web Page file subdirectories which satisfy an administrator-specified file subdirectory restriction, wherein said administrator-specified file subdirectory restriction is provided to said searching means by a prior administrative action.

18. A computing environment according to claim 10 wherein said searching means returns a set of results to said Web Browser after the search has been completed.

19. A computing environment according to claim 10 wherein said results are returned to said Web Browser in the form of HyperText Markup Language (HTML) source code.

20. Apparatus for dynamically providing Web Site status information to a Web Browser, wherein said Web Browser is connected to a Web Site via a gateway, said apparatus having:

a first communications component connecting said Web Browser to said gateway, wherein said first communications component passes a user generated search request to said gateway from said Web Browser, and a subsequent set of search results from said gateway to said Web Browser;

a search program residing on said gateway which accesses said Web Site through a second communications component, traverses a Web Page file hierarchy of said Web Site, generates said set of results which matches said search request, and returns said results to said gateway.

21. An apparatus of claim 20 wherein said Web Site status information returned by said search program includes a table of Web Pages that have been recently updated based upon a user-supplied threshold date criteria.

22. An apparatus according to claim 21 wherein said returned Web Site status information is administrator-tailorable.

23. An apparatus of claim 21 wherein said table of Web Pages includes links to said recently updated Web Pages.
