Abstract

A method and apparatus enables accessing of the Internet by multiple users of a common device. Each user'"'"'s cached information is uploaded to a predetermined server as part of a log-off process. Each user'"'"'s cached information is also downloaded from the predetermined server as part of a log-on process. A processor in the common device executes a multi-user management process manages the users'"'"' cached information. The multi-user management process stores the user'"'"'s cached information in local memory upon downloading it from the predetermined server, thereby enabling a browser application to function as if customized by each user. The browser application retrieves the cached information stored in local memory and updates the cached information during its logon session with a particular user, thereby ensuring the cached information remains up to date.

Claims

1. An apparatus for accessing the Internet by multiple users comprising:

a processor to execute a multi-user management process that uploads cached information to a predetermined server on the Internet when each user logs out and downloads cached information for each user when each user logs on; and

a browser application to access the Internet and including a plurality of user-specific settings and history being stored in the cached information.

2. The apparatus according to claim 1, wherein the cached information includes a user'"'"'s address book, and one or more bookmarks.

3. The apparatus according to claim 1, wherein the cached information includes one or more cookies.

4. The apparatus according to claim 1, wherein the cached information includes history information for a user.

5. The apparatus according to claim 1, further comprising a memory to store a user'"'"'s cached information after downloading the user'"'"'s cached information by the multi-user management process.

6. The apparatus according to claim 5, wherein said multi-user management process clears a user'"'"'s cached information from said memory after successfully uploading the user'"'"'s cached information.

7. The apparatus according to claim 5, wherein said memory comprises a memory stick.

8. The apparatus according to claim 5, wherein said memory comprises flash memory.

9. The apparatus according to claim 5, wherein said browser application updates the user'"'"'s cached information in said memory.

10. The apparatus according to claim 5, wherein said memory comprises a ring buffer.

11. A method for accessing a computer network by multiple users of a common device comprising:

uploading user cached information for a particular user to a predetermined server on the computer network upon said particular user logging out; and

downloading user cached information for the particular user when said particular user logs in.

12. The method according to claim 11, further comprising storing the user cached information for a particular user in a memory of the common device when the particular user is logged on.

13. The method according to claim 12, further comprising clearing the user cached information from the memory in the common device after uploading the user cached information.

14. The method according to claim 11, further comprising storing the user cached information in a removable memory stick that is insertable into the common device.

15. The method according to claim 11, further comprising storing the user cached information in a flash memory of the common device.

16. The method according to claim 11, further comprising storing the user cached information in a ring buffer of the common device.

17. The method according to claim 11, further comprising updating the user cached information stored in the memory of the common device when a user is logged onto the computer network.

18. The method according to claim 11, wherein the local cached information includes user specific preferences and data associated with a browser application to be executed by the common device.

19. The method according to claim 18, wherein the local cached information stored in the memory of the common device is updated by the browser when the browser accesses the computer network.

20. The method according to claim 11, wherein the cached information includes a user'"'"'s address book, and one or more bookmarks.

21. The method according to claim 11, wherein the cached information includes one or more cookies.

22. The method according to claim 11, wherein the cached information includes history information for a user.

24. The method according to claim 23, further comprising maintaining a file for each user on the predetermined server of a plurality of common devices.

25. The method according to claim 23, further comprising uploading a second user'"'"'s cache data to the predetermined server when said second user logs off the common device.

26. The method according to claim 25, further comprising downloading the second user'"'"'s cache data from the predetermined server to a local memory in the common device when said second user logs on the common device.

27. The method according to claim 24, further comprising creating a file for a particular user on the predetermined server for storing the particular user'"'"'s cache data when said particular user logs off the common device after an initial registration process.

23. A method for managing multiple users of a common device comprising:

providing a predetermined server for storing user cache data;

uploading a first user'"'"'s cache data to the predetermined server when said first user logs off the common device; and

downloading a first user'"'"'s cache data from the predetermined server when saud first user logs on the common device.
