Abstract

A method and system for increasing perceived Internet browser performance by using a relatively high-bandwidth data source such as a CD-ROM and/or a hard drive directory as a local cache of Internet content. The content is provided by content providers via some high-bandwidth data source such as a CD-ROM media for a CD-ROM drive. An install program provided with the content registers with the system one or more URL patterns such as prefixes corresponding to the content, in association with one or more file system patterns (e.g., prefixes) corresponding to a cache container (file system directory). When subsequently browsing to a URL having a matching pattern, the URL pattern is resolved to the cache container, which is then used with the rest of the URL to construct a local file reference. The local file is accessed from the high-bandwidth data source. If the local file is not found, the original http URL is instead used, whereby the content is downloaded in the normal manner. The installable cache may reside on a CD-ROM or other removable media, whereby an autorun program or script that executes each time the media is inserted into a drive updates the registered drive letter.

Claims

In a computer system configured to access network content via network access software over a network connection, a method of accessing content, comprising, providing content that corresponds to the network content at a data source that is installable independent of a cache of the network access software, at least some of the content not having been downloaded via the network connection, receiving a request to access the content, the request including a network reference of the content, converting the network reference to a local reference, and accessing the content from the data source based on information corresponding to the local reference.

2. The method of claim 1 wherein converting the network reference to a local reference, registering mapping information in the system, the mapping information comprising information corresponding to the network reference of the content in association with information corresponding to a local reference of the content, and looking up the mapping information using information corresponding to the network reference to obtain the information corresponding to the local reference associated therewith.

3. The method of claim 2 wherein the network reference comprises a uniform resource locator (URL), and wherein registering information corresponding to the network reference of the content in association with information corresponding to a local reference of the content, comprises, registering a pattern corresponding to the URL in conjunction with a file system pattern corresponding to a container of a file system of the computer system.

4. The method of claim 3 wherein looking up the mapping information comprises, determining a URL pattern based on the URL received in the request, and using the URL pattern to retrieve the file system pattern.

5. The method of claim 3 wherein the URL pattern is a prefix and the file system pattern is a prefix.

6. The method of claim 3 wherein accessing the content includes, constructing a file system path and filename from the file system pattern and the URL, and retrieving content via the file system from the path and filename.

7. The method of claim 6 wherein the file system pattern includes a drive identifier, wherein providing content includes providing a physical medium which can be read by a device of the system, the device referenced by a drive identifier of the file system, and further comprising, detecting the medium in the device, and updating the drive identifier in the file system pattern based on the drive identifier of the device.

8. The method of claim 1 wherein providing content includes providing a physical medium which can be read by a device of the computer system.

9. The method of claim 8 wherein the physical medium comprises a CD-ROM and the device comprises a CD-ROM reader.

10. The method of claim 1 wherein accessing the content includes reading the content from a physical medium.

11. The method of claim 1 further comprising copying the content to a disk drive of the system.

12. The method of claim 11 further comprising indexing the location of the content copied to the disk drive.

13. A computer-readable medium having computer-executable instructions for performing the method of claim 1.

14. In a computer system configured to access network content via network access software over a network connection, a system for accessing content, comprising, a data source installable independent of a cache of the network access software, the data source including content corresponding to the network content, at least some of the content not having been downloaded via the network connection, the network access software receiving a request to access the content, the request including a network reference, a conversion mechanism for obtaining a local reference based on the network reference, and an interface for accessing the content from the data source based on the local reference.

15. The system of claim 14 wherein the conversion mechanism comprises a registry of mappings, each mapping including information corresponding to the network reference of the content in association with information corresponding to the local reference of the content, and a look-up mechanism for obtaining the information corresponding to the local reference from the mapping information based on the information corresponding to the network reference.

16. The system of claim 15 wherein the network reference comprises a uniform resource locator (URL), and wherein the registry has registered therein a pattern corresponding to the URL in conjunction with a file system pattern corresponding to a container of a file system of the computer system.

17. The system of claim 16 further comprising a mechanism for constructing a file system path and filename from the file system pattern and the URL, and for providing the path and filename to the interface.

18. The system of claim 16 wherein the file system pattern includes a drive identifier, wherein the data source comprises a device referenced by a drive identifier of the file system, and further comprising a program for updating the drive identifier in the file system pattern based on the drive identifier of the device.

19. The system of claim 16 wherein the pattern corresponding to the URL is a prefix and the file system pattern is a prefix.

20. The system of claim 14 wherein the data source comprises a physical medium in conjunction with a media-reading a device of the computer system.

21. The system of claim 20 wherein the physical medium comprises a CD-ROM and the media-reading device comprises a CD-ROM reader.

22. The system of claim 14 further comprising a storage medium, and wherein the interface further copies the content to the storage medium.

23. The system of claim 22 further comprising an index for recording the location of the content copied to the storage medium.

24. In a computer system configured to access network content identified by a Uniform Resource Locator (URL) via a first connection, a method of accessing content, comprising, providing content corresponding to the network content at a media-reading device of the system that provides data at a rate which is relatively faster than the first connection, at least some of the content not having been downloaded via the first connection, registering a URL pattern in association with a file system pattern, the URL pattern based on the URL of the network content, receiving a request to access the content, the request including the URL, looking up the file system pattern using the URL pattern, and accessing the content from the media-reading device using a file system path and filename based on the file system pattern information and the URL.

25. The method of claim 24 wherein the step of looking up the file system pattern comprises the step of determining a URL pattern based on the URL received in the request.

26. The method of claim 24 wherein URL pattern is a prefix and the file system pattern is a prefix.
