Abstract

Method and system for providing improved uniform resource locator (URL) mangling performance using fast re-write including scanning a web page, detecting an absolute URL in the web page, and modifying the detected absolute URL to a corresponding relative URL in the web page, is disclosed.

Claims

1. A method of providing uniform resource locator (URL) mangling, comprising the steps of:

scanning a web page;

detecting an absolute URL in the web page; and

modifying the detected absolute URL to a corresponding relative URL in the web page.

2. The method of claim 1 wherein the step of detecting an absolute URL includes the step of detecting a “

;

”

in the URL.

3. The method of claim 1 wherein the step of modifying the detected absolute URL includes the step of replacing a “

;

”

in the absolute URL with a predetermined character.

4. The method of claim 3 wherein the predetermined character includes an alphanumeric character.

5. The method of claim 1 further including the step of transmitting the web page after the modifying step.

6. A method of performing URL mangling, comprising:

receiving an access request to a web page;

receiving the requested web page;

detecting a URL in the web page; and

mangling the detected URL by replacing a colon in the detected URL with a predetermined character.

7. The method of claim 6 wherein the detected colon is located in the URL after the transmission protocol.

8. The method of claim 7 wherein the transmission protocol includes hyper text transmission protocol.

9. The method of claim 6 wherein the access request is received over a public data network.

10. The method of claim 6 wherein the requested web page is received over a private data network.

11. The method of claim 10 wherein the requested web page is received from a web server in the private data network.

12. A method of providing URL mangling, comprising:

detecting an absolute URL in a web page; and

performing URL mangling on the detected absolute URL by modifying the detected absolute URL to a relative URL.

13. The method of claim 12 wherein the performing URL mangling step includes the step of replacing a colon in the absolute URL with a predetermined character.

14. The method of claim 13 wherein the predetermined character includes an alphanumeric character.

15. The method of claim 12 wherein the step of detecting the absolute URL includes the steps of:

scanning the web page; and

identifying a colon in the URL.

16. The method of claim 15 wherein the colon is located immediately following the transmission protocol of the URL.

17. The method of claim 16 wherein the transmission protocol includes hyper text transmission protocol (http).

18. A system for providing URL mangling, comprising:

a server terminal; and

a gateway terminal operatively coupled to the server terminal, the gateway terminal configured to receive a web page from the server terminal, and further, wherein the gateway terminal is configured to scan the received web page, the gateway terminal further configured to modify an absolute URL in the web page to a relative URL.

19. The system of claim 18 wherein the gateway terminal includes a secure socket layer virtual private network (SSLVPN) gateway terminal.

20. The system of claim 18 wherein the gateway terminal is operatively coupled to a private data network including the server terminal.

21. The system of claim 18 further including a client terminal operatively coupled to the gateway terminal over a public data network.

22. The system of claim 18 wherein the gateway terminal is configured to transmit the web page with modified URL to the client terminal.

23. A system for providing URL mangling, comprising:

means for scanning a web page;

means for detecting an absolute URL in the web page; and

means for modifying the detected absolute URL to a corresponding relative URL in the web page.
