10. The web page fragmentation server proxy of claim 9, wherein each content tag of the content tags is used to create a separate received fragment.

11. The web page fragmentation server proxy of claim 10, wherein the processor is adapted to create a unique identifier for the received fragment.

12. The web page fragmentation server proxy of claim 11, wherein the processor is adapted to compare content of the received fragment with content of stored web page fragments, wherein the processor creates a new version number if the content of the received fragment does not match the content of the stored web page fragments.

13. The web page fragmentation server proxy of claim 12, wherein the memory is adapted to store received fragments where the unique identifier and version number do not correspond with the stored fragments.

14. The web page fragmentation server proxy of claim 8 wherein the processor compares a unique identifier and version number received from the mobile device with the unique identifier and version number of received fragments to determine fragments the mobile device does not have, said communication means forwarding fragments that the mobile device does not have.

15. A method, in a web page fragmentation server proxy having a processor, communication means and memory, of providing new and updated fragments to a mobile device, the mobile device requesting a web page with the request including fragment identifiers for fragments of the web page already stored by the mobile device, the method comprising the steps of:

receiving a web page from the internet corresponding with the web page requested by the mobile device;

fragmenting the received web page to create received fragments;

comparing received fragments with fragments stored in the memory, the fragments not matching the memory being new fragments;

storing new fragments; and

passing stored fragments for the requested web page with different fragment identifiers to those stored on the mobile device to the mobile device.

16. The method of claim 15, wherein the fragmenting step comprises looking for fragmentation tags within the received web page and fragmenting based on the fragmentation tags.

17. The method of claim 16 wherein the fragment identifiers include unique identifiers and version numbers, the comparing step utilizing the unique identifiers and version numbers within the fragmentation tags to compare received fragments with the identifiers for fragments.

18. The method of claim 17, further storing new fragments, wherein the storing step stores received fragments with a different unique identifier and version number from the unique identifier and version number of any stored fragments.

19. The method of claim 15, wherein the fragmenting step comprises looking for content tags within the received web page and fragmenting based on the content tags.

20. The method of claim 19, wherein the content tags are selected from the group consisting of frames, frame sets, tables, forms, objects, images and scripts.

21. The method of claim 20, wherein each content tag is used to create a received fragment.

22. The method of claim 21, wherein the comparing step compares the content of the received fragment with the identifiers for fragments, wherein the content of received fragments no matching the content of stored fragments designates a new fragment.

23. The method of claim 15 wherein the passing step further comprises the steps of filtering fragments based on a priority assigned to the fragments, wherein the passing step only passes filtered fragments.

24. The method of claim 23, wherein the priority is assigned within the web page.

25. The method of claim 23, wherein the priority is assigned based on a content tag type.

26. A method of browsing on a mobile device comprising the steps of:

sending, from the mobile device, a web page request with fragment identifiers of fragments stored on the mobile device;

receiving, at a web page fragmentation server proxy the web page request;

sending the web page request to the internet;
