Abstract

A system and method for on-the-fly rewriting of a plurality of URLs in a Web-page is disclosed herein. On a server-side, the present invention analyzes a plurality of hyperlinks of the Web-page and optimizes the plurality of hyperlinks of the Web-page to generate an optimized Web-page, which is then transmitted to a client-side.

Claims

1. A method for on-the-fly rewriting of a plurality of URLs in a webpage, the method comprising:

receiving a request for a webpage from a client-side of a network;

retrieving the webpage at a server-side of the network, the webpage comprising a plurality of hyperlinks, an original code that includes code that is tagged to be performed by the client-side, and one or more functions set to run at the server-side;

analyzing the plurality of hyperlinks of the webpage at the server-side, wherein the analyzing comprises parsing the webpage at the server-side;

optimizing the plurality of hyperlinks of the webpage without affecting the original code of the webpage to generate an optimized webpage at the server-side;

identifying a first function of the one or more functions that is set to run at the server-side and also set to run at the client-side and not stripping the code of the first function;

stripping code from at least one of the one or more functions set to run at the server-side and not also set to run at the client-side;

transmitting the optimized webpage with the original code, and without the code that was stripped from the at least one function, from the server-side to the client-side over the network; and

performing the code that is tagged to be performed by the client-side.

2. The method according to claim 1 wherein the plurality of hyperlinks comprises a plurality of pseudo-hyperlinks.

3. The method according to claim 1 wherein the step of optimizing the plurality of hyperlinks of the webpage comprises substituting shorter links for each of the plurality of hyperlinks.

4. The method according to claim 1 wherein the step of optimizing the plurality of hyperlinks of the webpage comprises changing each of the plurality of hyperlinks to shift a load to at least one different server.

5. The method according to claim 1 wherein the step of optimizing the plurality of hyperlinks of the webpage comprises rerouting at least one of the plurality of hyperlinks.

6. The method according to claim 1 wherein the plurality of hyperlinks comprises a plurality of pseudo-hyperlinks and the optimizing the plurality of hyperlinks of the webpage comprises substituting shorter links for each of the plurality of pseudo-hyperlinks.

7. The method according to claim 1 wherein the original code is JavaScript Code.

8. The method according to claim 1 wherein a first function of the one or more functions set to run at the server-side comprises a runat attribute set to “

server” and

the code of the first function is stripped and a second function of the one or more functions set to run at the server-side comprises a runat attribute set to “

both,” and

the code of the second function is not stripped.

9. A computer program fixed on a non-transitory computer readable medium of a server for on-the-fly rewriting of a plurality of URLs in a webpage, wherein the computer program, when executed by the server, causes the server to:

retrieve a webpage comprising a plurality of hyperlinks, an code tagged to be performed by a client-side of a network, and one or more functions set to run at a server-side of the network;

analyze the plurality of hyperlinks of the webpage and parse the webpage at the server-side of the network;

optimize the plurality of hyperlinks of the webpage without affecting the code tagged to be performed by the client-side of the network to generate an optimized webpage on the server-side;

remove code from at least one of the one or more functions set to run at the server-side and not remove code of a first function of the one or more functions because the first function comprises a runat attribute set to “

both”

; and

transmit the optimized webpage with the code tagged to be performed by the client-side of the network, and without the code that was removed from the at least one function, over the network from the server-side to a web-browser of the client-side of the network.

10. The computer program according to claim 9 that, when executed by the server, causes the server to reroute at least one of the plurality of hyperlinks.

11. The computer program according to claim 9 that, when executed by the server, causes the server to change each of the plurality of hyperlinks to shift a load to at least one different server.

12. The computer program according to claim 9 that, when executed by the server, causes the server to substitute shorter links for each of the plurality of hyperlinks.

13. A system for on-the-fly rewriting of a plurality of URLs in a webpage, the system comprising:

a first server computer located on a server-side of a network and being configured to;

receive a request over the network from a web browser on a client-side of the network for a webpage that includes a plurality of hyperlinks, an original code that includes code that is tagged to be performed by the client-side and code that is tagged to be performed by only the server-side; and

process code that is tagged to be performed by the server-side to serve the webpage to the web browser over the network, the code including one or more functions executable by at least one of the server-side and the client-side; and

a second server computer located on the server-side of the network and being configured to;

retrieve the webpage from the first server,

analyze the plurality of hyperlinks of the webpage by parsing the webpage at the server-side of the network,

optimize the plurality of hyper links of the webpage without affecting the code that is tagged to be performed by the client-side to generate an optimized webpage on the server-side of the network,

identify a first function of the one or more functions that is set to run at the server-side and also set to run at the client-side and not strip the code of the first function,

strip code from at least one of the one or more functions set to run at the server-side and not also set to run at the client-side, and

transmit the optimized webpage with the code that is tagged to be performed by the client-side from the server-side to the web browser on the client-side over the network, wherein one of the first or second server computers is further configured to strip the code that is tagged to be performed by only the server-side.

14. The system according to claim 13 wherein the plurality of hyperlinks comprises a plurality of pseudo-hyperlinks.

15. The system according to claim 13 wherein the second server is configured to substitute shorter links for each of the plurality of hyperlinks.

16. The system according to claim 13 wherein the second server is configured to change each of the plurality of hyperlinks to shift a load to at least one different server.

17. The system according to claim 13 wherein the second server is configured to reroute at least one of the plurality of hyperlinks.

18. The system of claim 13 wherein the first server comprises the second server.
