Abstract

Various embodiments are described for content indicators to accelerate detection of a changed web page or other file.

Claims

1. An apparatus comprising:

an authoring tool to generate files;

a calculator to calculate a content indicator for one or more of the files, the page authoring tool to store each of the calculated content indicators with a corresponding file.

2. The apparatus of claim 1 wherein the authoring tool comprises a HTML authoring tool or program.

3. The apparatus of claim 1 wherein the calculator comprises a digest calculator to calculate digests for each of the files.

4. The apparatus of claim 1 wherein the apparatus encodes each of the content indicators within a corresponding file.

5. An apparatus comprising:

an insertion tool comprising a calculator to calculate a content indicator for each of a plurality of files, the insertion tool to insert each of the calculated content indicators within a corresponding one of the files.

6. The apparatus of claim 5 wherein the calculator comprises a digest calculator to calculate digests for each of the files.

7. The apparatus of claim 5 wherein the apparatus encodes each of the content indicators within a corresponding file.

9. The apparatus of claim 5 wherein the files comprise one or more of the following:

web pages;

HTML pages;

Graphics; and

Scripts.

8. The apparatus of clam 6 wherein the insertion tool comprises an insertion tool to insert each of the calculated digests within a corresponding one of the files.

10. An apparatus comprising:

an insertion tool comprising a calculator to calculate a content indicator for each of a plurality of files, the insertion tool to obtain a path for each file and store a file path and the content indicator in a repository for each of a plurality of files.

11. The apparatus of claim 10 wherein the calculator comprises a digest calculator to calculate digests for each of a plurality of files.

12. The apparatus of claim 11 wherein the calculator comprises a digest calculator to calculate digests for each of a plurality of web pages.

13. The apparatus of claim 10 wherein the path file indicates a location or address of the file.

15. The method of claim 14 wherein the calculating comprises calculating a digest for the file.

16. The method of claim 15 wherein the storing comprises storing the digest with the file to provide content change indication for the file when compared to another digest.

17. The method of claim 14 and further comprises:

retrieving the content indicator for the file;

comparing the content indicator for the file to a content indicator corresponding to a previous version of the file; and

determining whether the file has changed based on the comparing.

18. The method of claim 14 and further comprises:

retrieving the content indicator for the file;

comparing the content indicator for the file to a content indicator corresponding to a previous version of the file; and

retrieving the file if the content indicator for the file and the content indicator corresponding to a previous version of the file do not match.

19. The method of claim 18 and further comprising updating an index based on the retrieved file if there was not a match.

14. A method comprising:

generating a file;

calculating a content indicator for the file;

storing the content indicator with the file to provide content change indication for the file when compared to another content indicator.

20. A method comprising:

obtaining a path for a file;

retrieving the file;

calculating a content indicator for the file;

storing the file path and the content indicator for the file in a repository or storage.

21. The method of claim 20 wherein the calculating comprises calculating a digest for the file.

22. The method of claim 21 wherein the storing comprises storing the file path and the digest in a digest repository or storage.

24. The apparatus of claim 23 wherein the calculator comprises calculating a digest for the file.

25. The apparatus of claim 23 wherein the storing comprises storing the digest with the file to provide content change indication for the file when compared to another digest.

27. The apparatus of claim 26 wherein the calculating comprises calculating a digest for the file.

28. The apparatus of claim 27 wherein the storing comprises storing the file path and the digest in a digest repository or storage.

23. An apparatus comprising a readable media having instructions thereon, the instructions resulting in the following when executed:

generating a file;

calculating a content indicator for the file;

storing the content indicator with the file to provide content change indication for the file when compared to another content indicator.

26. An apparatus comprising a readable media having instructions thereon, the instructions resulting in the following when executed:

obtaining a path for a file;

retrieving the file;

calculating a content indicator for the file;

storing the file path and the content indicator for the file in a repository or storage.
