Abstract

Systems and methods for script injection are shown and described. The method can include intercepting, by a network appliance, a request for a web page from a computing device, transmitting, by the network appliance, the request for a web page to a web server, and intercepting, by the network appliance, a response from the web server, the response including at least a portion of the requested web page. The method can also include injecting, by the network appliance, a script having instructions that when executed by the computing device registers to be notified of the occurrence of a web page event thereby creating a modified response and transmitting the modified response to the computing device that requested the web page.

Claims

1. A method of measuring parameters associated with loading a web page, the method comprising

intercepting, by a network appliance, a request for a web page from a computing device;

transmitting, by the network appliance, the request for a web page to a web server;

intercepting, by the network appliance, a response from the web server, the response including at least a portion of the requested web page;

injecting, by the network appliance, a script having instructions that when executed by the computing device registers to be notified of the occurrence of a web page event thereby creating a modified response; and

transmitting the modified response to the computing device that requested the web page.

2. The method of claim 1 further comprising accelerating, by the network appliance, at least one of the intercepted request for a web page from the computing device, the intercepted response from the web server;

and the modified response to the computing device.

3. The method of claim 2 wherein the accelerating comprises compressing at least one of the intercepted request for a web page from the computing device, the intercepted response from the web server;

and the modified response to the computing device.

4. The method of claim 2 wherein the accelerating comprises applying, by the network appliance, transmission control protocol pooling.

5. The method of claim 2 wherein the accelerating comprises applying, by the network appliance, transmission control protocol multiplexing.

6. The method of claim 2 wherein the accelerating comprises applying, by the network appliance, transmission control protocol buffering.

7. The method of claim 2 wherein the accelerating comprises caching, by the network appliances, at least a portion of content of the requested web page.

8. A computer readable medium having instructions thereon what when executed measure parameters associated with loading a web page, the computer readable medium comprising:

instructions to intercept, by a network appliance, a request for a web page from a computing device;

instructions to transmit, by the network appliance, the request for a web page to a web server;

instructions to intercept, by the network appliance, a response from the web server, the response including at least a portion of the requested web page;

instructions to inject, by the network appliance, a script having instructions that when executed by the computing device registers to be notified of the occurrence of a web page event thereby creating a modified response; and

instructions to transmit the modified response to the computing device that requested the web page.

9. The computer readable medium of claim 8 further comprising instructions to accelerate, by the network appliance, at least one of the intercepted request for a web page from the computing device, the intercepted response from the web server;

and the modified response to the computing device.

10. The computer readable medium of claim 9 wherein the instructions to accelerate comprise instructions to compress at least one of the intercepted request for a web page from the computing device, the intercepted response from the web server;

and the modified response to the computing device.

11. The computer readable medium of claim 9 wherein the instructions to accelerate comprise instructions to apply, by the network appliance, transmission control protocol pooling.

12. The computer readable medium of claim 9 wherein the instructions to accelerate comprise instructions to apply, by the network appliance, transmission control protocol multiplexing.

13. The computer readable medium of claim 9 wherein the instructions to accelerate comprise instructions to apply, by the network appliance, transmission control protocol buffering.

14. The computer readable medium of claim 9 wherein the instructions to accelerate comprises instructions to cache, by the network appliances, at least a portion of content of the requested web page.

15. A system for measuring parameters associated with loading a web page, the system comprising

means for intercepting, by a network appliance, a request for a web page from a computing device;

means for transmitting, by the network appliance, the request for a web page to a web server;

means for intercepting, by the network appliance, a response from the web server, the response including at least a portion of the requested web page;

means for injecting, by the network appliance, a script having instructions that when executed by the computing device registers to be notified of the occurrence of a web page event thereby creating a modified response; and

means for transmitting the modified response to the computing device that requested the web page.

16. The system of claim 15 further comprising means for accelerating, by the network appliance, at least one of the intercepted request for a web page from the computing device, the intercepted response from the web server;

and the modified response to the computing device.

17. The system of claim 16 wherein the means for accelerating comprise means for compressing at least one of the intercepted request for a web page from the computing device, the intercepted response from the web server;

and the modified response to the computing device.

18. The system of claim 16 wherein the means for accelerating comprise means for applying, by the network appliance, transmission control protocol pooling.

19. The system of claim 16 wherein the means for accelerating comprise means for applying, by the network appliance, transmission control protocol multiplexing.

20. The system of claim 16 wherein the means for accelerating comprise means for applying, by the network appliance, transmission control protocol buffering.

21. The system of claim 16 wherein the means for accelerating comprise means for caching, by the network appliances, at least a portion of content of the requested web page.
