Abstract

A method and system of storing and accessing documents on a computer file system utilizing a file system-independent key for use in an index-less browser caching mechanism. The present invention is a method and system for storing a resource such as a document or group of documents on a computer file system using a Universal Resource Indicator (URI) as the file name by generating a unique system-independent key from the URI for use in an index-less browser caching system. The invention takes into account the various file entry length limitations enforced by each unique file system by converting the specified URI into a key containing hexadecimal values of the key'"'"'s characteristics. In this fashion, an index-less browser caching system such as a Web browser of a VoiceXML browser is created that is file system-independent.

Claims

1. A method of constructing a system-independent key from a universal resource indicator for use in an index-less caching system, the method comprising:

converting, in an index-less caching mechanism executing in memory by a processor of a computer, characters of the universal resource indicator to equivalent values resulting in a value string having a value string length, the value string including a file name associated with a cached resource;

determining by the index-less caching mechanism if the value string length exceeds a predetermined maximum file entry length for the caching system; and

converting by the index-less caching mechanism the value string into discrete file entries including one or more directory entries and the file name associated with the cached resource, wherein each discrete file entry contains a number of values equal to or less than the maximum file entry length.

2. The method of claim 1 wherein the index-less caching system is a Web browser.

3. The method of claim 1 wherein the index-less caching system is a VoiceXML browser.

4. The method of claim 1 wherein the equivalent values are alphanumeric values.

5. The method of claim 4 wherein the alphanumeric values are hexadecimal values.

6. A machine readable storage medium storing a computer program which when executed constructs a system-independent key from a universal resource indicator for use in an index-less caching system, the computer program performing a method comprising:

converting characters of the universal resource indicator to equivalent values resulting in a value string having a value string length, the value string including a file name associated with a cached resource;

determining if the value string length exceeds a predetermined maximum file entry length for the caching system; and

converting the value string into discrete file entries including one or more directory entries and the file name associated with the cached resource, wherein each discrete file entry contains a number of values equal to or less than the maximum file entry length.

7. The machine readable storage medium of claim 6, wherein the index-less caching system is a Web browser.

8. The machine readable storage medium of claim 6, wherein the index-less caching system is a VoiceXML browser.

9. The machine readable storage medium of claim 6, wherein the equivalent values are alphanumeric values.

10. The machine readable storage medium of claim 9, wherein the alphanumeric values are hexadecimal values.

11. A system for constructing a system-independent key from a universal resource indicator for use in an index-less caching system, the system comprising a computer having:

a database, the database storing a cached resource, the location of the cached resource identified by a universal resource indicator; and

a computer with a memory and a central processing unit coupled to the database, converting characters of the universal resource indicator to equivalent values resulting in a value string having a value string length, the value string including a file name associated with a cached resource, the central processing unit further determining if the value string length exceeds a maximum file entry length for the caching system, and converting the value string into discrete file entries including one or more directory entries and the file name associated with the cached resource, wherein each discrete file entry contains a number of values equal to or less than the maximum file entry length.

12. The system of claim 11, wherein the index-less caching system is a Web browser.

13. The system of claim 11, wherein the index-less caching system is a VoiceXML browser.

14. The system of claim 11, wherein the equivalent values are alphanumeric values.

15. The system of claim 14, wherein the alphanumeric values are hexadecimal values.
