Abstract

A method and system for acceleration of access to a web page using next page optimization, caching and pre-fetching techniques. The method comprises receiving a web page responsive to a request by a user; analyzing the received web page for possible acceleration improvements of the web page access; generating a modified web page of the received web page using at least one of a plurality of pre-fetching techniques; providing the modified web page to the user, wherein the user experiences an accelerated access to the modified web page resulting from execution of the at least one of a plurality of pre-fetching techniques; and storing the modified web page for use responsive to future user requests.

Claims

1. A system for acceleration of access to web pages, comprising:

a network interface enabling communication of one or more user nodes with one or more web servers over a network for accessing web pages stored in the one or more web servers;

an acceleration server coupled to the network interface for accelerating access to the web pages to the one or more user nodes using at least one pre-fetching technique;

a first cache connected to the acceleration server and the one or more user nodes and operative to cache information associated with requests directed from the one or more the user nodes to the acceleration server;

a second cache connected to the acceleration server and the one or more web servers and operative to cache information associated with requests directed from the one or more web servers to the acceleration server; and

a memory coupled to the acceleration server and containing a plurality of instructions respective of the at least one pre-fetching technique.

2. The system of claim 1, wherein the at least one pre-fetching technique comprises:

determining a next web page that is likely to be accessed next by a user node based on a previous accessed web page; and

pre-fetching the next web page from the one or more web servers.

3. The system of claim 2, further comprises:

inserting into the next web page code enabling to pre-fetch different resources upon each access to the next web page; and

storing the modified next web page in the first cache.

4. The system of claim 1, wherein the acceleration server intercepts the web page and parses the web page prior to sending the web page to one or more of the user nodes.

5. The system of claim 1, wherein the at least one pre-fetching technique comprises:

adding to the received web page code for detecting a mouse presence over a universal resource link (URL); and

storing the modified web page in the first cache.

6. The system of claim 5, wherein the acceleration server further comprises a timer for determining if the mouse presence over the URL was longer than a predefined threshold prior to pre-fetching content.

7. The system of claim 1, wherein the at least one of the pre-fetching technique comprises:

checking if a requested web page was accessed within the web site of the web page or if the requested web page was accessed from outside of the web site of the web page.

8. The system of claim 7, further comprises:

pre-fetching at least a missing resource of the web page, when the requested web page was accessed from outside of the web site of the web page.

9. The system of claim 1, wherein the at least one pre-fetching technique comprises:

determining for a web page its static portions and dynamic portions;

retrieving from the first cache the static portions; and

generating at least a request to receive the dynamic portions from the one or more web servers.

10. The system of claim 1, wherein the at least one pre-fetching technique comprises:

adding a version indicator to a web page; and

providing a requested web page to one of the user nodes from a web server only if there is a difference between the version indicator of the requested web page and a cached version in the first cache.

11. The system of claim 10, wherein said version indicator is comprised from a plurality of sub-indicators.

12. The system of claim 11, wherein a sub-indicator is provided for each resource of the web page, thereby enabling an identification of what has changed in the web page and providing to the user only those resources that have changed.

13. The system of claim 1, wherein the acceleration server collects statistics about link usage of each of the links for at least a web page.

14. The system of claim 13, wherein responsive of accessing the at least web page the acceleration server fetches web pages of those links within the at least web page that are likely to be used based on the collected statistics.

15. The system of claim 1, wherein the acceleration server determines for a plurality of web pages common parts of the web pages and sends to a user of said one or more user nodes the common parts only once and causing each subsequent web page of the plurality of web page to use the common parts previously provided.

17. The method of claim 1, wherein one of the plurality of pre-fetching techniques comprises:

determining a next web page that is likely to be accessed next by a user node based on a previous accessed web page; and

pre-fetching the next web page from a web server.

18. The method of claim 17, further comprises:

inserting to the next web page code enabling to pre-fetch different resources upon each access to the next web page; and

storing the modified next web page in a memory.

16. A method for acceleration of access to a web page, comprising:

receiving a web page responsive to a request by a user;

analyzing the received web page for possible acceleration improvements of the web page access;

generating a modified web page of the received web page using at least one of a plurality of pre-fetching techniques;

providing the modified web page to the user, wherein the user experiences an accelerated access to the modified web page resulting from execution of the at least one of a plurality of pre-fetching techniques; and

storing the modified web page for use responsive to future user requests.

19. The method of claim 16, further comprises:

intercepting the web page and parsing the intercepted web page prior to sending the web page to a user node.

20. The method of claim 16, wherein one of the plurality of pre-fetching techniques comprises:

adding to the received web page code for detecting a mouse presence over a universal resource link (URL); and

storing the modified web page in a memory.

21. The method of claim 20, further comprises:

determining using a timer if the mouse presence over the URL was longer than a predefined threshold; and

pre-fetching content respective of the URL when the timer'"'"'s measure is longer than the predefined threshold.

22. The method of claim 16, wherein one of the plurality of pre-fetching techniques comprises:

checking if a requested web page was accessed within the web site of the web page or if the requested web page was accessed from outside of the web site of the web page.

23. The method of claim 22, further comprises:

pre-fetching at least a missing resource of the web page, when the requested web page was accessed from outside of the web site of the web page.

24. The method of claim 16, wherein one of the plurality of pre-fetching techniques comprises:

determining for a web page its static portions and dynamic portions;

retrieving from a local memory the static portions; and

generating at least a request to receive the dynamic portions from a web server.

25. The method of claim 16, wherein one of the plurality of pre-fetching techniques comprises:

adding a version indicator to a web page; and

providing a requested web page to a user from a web server, only if there is a difference between the version indicator of the requested web page and a version indicator of a cached version of the requested web page.

26. The method of claim 25, wherein said version indicator is comprised from a plurality of sub-indicators.

27. The method of claim 26, wherein a sub-indicator is provided for each resource of the web page, thereby enabling an identification of what has changed in the web page and providing to the user only those resources that have changed.

28. The method of claim 16, further comprises:

collecting statistics about link usage of each of the links in at least a web page.

29. The method of claim 28, further comprises:

fetching web pages of those links in the at least web page that are likely to be used based on the collected statistics.
