Abstract

A method of display modification in a client server web system, comprising, intercepting, by a web intermediary, a response to a client request, sent by a server in response to the request, the response including client side active content adapted to execute at a browsing software on a client computer; replacing at least one display-related code section in said response by a wrapper section that includes code for modification of at least one display element and code for executing the original display-related code section; and executing said wrapper section as client side active content at said client to generate a display, modified from a display that would have been generated by executing the response.

Claims

1. A method of display modification in a client server web system, comprising:

intercepting, by a web intermediary, a response to a client request, sent by a server in response to the request, the response including client side active content adapted to execute at a browsing software on a client computer;

replacing at least one display-related code section in said response by a wrapper section that includes code for modification of at least one display element and code for executing the original display-related code section; and

executing said wrapper section as client side active content at said client to generate a display, modified from a display that would have been generated by executing the response.

2. A method according to claim 1, wherein said web intermediary comprises a proxy.

3. A method according to claim 2, wherein said proxy comprises a transparent proxy.

4. A method according to claim 2, wherein said proxy comprises a front-end proxy.

5. A method according to claim 2, wherein said proxy comprises a reverse proxy.

6. A method according to claim 1, wherein said web intermediary comprises a web server.

7. A method according to claim 1, wherein said intercepted client side active content comprises JavaScript.

8. A method according to claim 7, wherein said code section comprises a document.write or writeln call.

10. A method according to claim 1, wherein said intercepted client side active content comprises Java.

11. A method according to claim 1, wherein said intercepted client side active content comprises Flash.

12. A method according to claim 1, wherein said intercepted client side active content is in a separate file in said response.

13. A method according to claim 1, wherein said intercepted client side active content is embedded in said response.

14. A method according to claim 1, wherein said code section comprises a function call, procedure or method.

15. A method according to claim 14, wherein said wrapper receives at least one parameter of said function, procedure or method.

17. A method according to claim 14, wherein said wrapper modifies a return value of said function, procedure or method.

18. A method according to claim 14, wherein said function, procedure or method is a funnel function through which display by said intercepted active content is funneled.

19. A method according to claim 1, wherein said code section comprises one or more commands.

20. A method according to claim 1, wherein replacing comprises overloading a function definition.

22. A method according to claim 1, wherein replacing comprises replacing portions of code inline.

24. A method according to claim 1, wherein replacing comprises providing said wrapper section as a separate file.

25. A method according to claim 1, wherein said wrapper section is a call to a subroutine.

26. A method according to claim 1, wherein said wrapper section is an in-line code section other than a mere subroutine call.

27. A method according to claim 1, wherein replacing comprises adding at least one watch on at least one variable of said intercepted active content.

28. A method according to claim 1, wherein said wrapper takes global variables into account by modifying at least one global variable.

30. A method according to claim 28, wherein said wrapper also further modifies a global variable back to a previous value from before said modifying.
