Abstract

Claims (65)

1. A computing device comprising:

a processor; and

memory storing programming instructions structured to cause the processor to:

send a request for a first resource to a proxy computing device;

receive a modified version of the first resource from the proxy computing device, the modified version of the first resource comprising an embedding function and a code rewriting function not included in the first resource;

detect an event associated with the embedding function and a code component;

insert, by the embedding function, a placeholder in the code component, resulting in a first modified version of the code component;

verify an authentication credential;

determine a placeholder value indicating the authentication credential is verified; and

replace, by the code rewriting function, the placeholder in the first modified version of the code component with the placeholder value, resulting in a second modified version of the code component.

2. The computing device of claim 1 , wherein the first resource comprises a web page, the modified version of the first resource comprises a modified version of the web page, and the programming instructions are further structured to cause the processor to:

present the modified version of the web page in a browser executed by the computing device.

3. The computing device of claim 1 , wherein the programming instructions are further structured to cause the processor to utilize a client-side proxy service to execute the embedding function and the code rewriting function.

4. The computing device of claim 3 , wherein the client-side proxy service is configured with the placeholder device, and to determine the placeholder value, the programming instructions are structured to cause the processor to:

determine the placeholder value based on the configuration of the client-side proxy service.

5. The computing device of claim 3 , wherein the programming instructions are further structured to cause the processor to:

receive the client-side proxy service from the proxy computing device.

6. The computing device of claim 1 , wherein to determine the placeholder value, the programming instructions are further structured to cause the processor to:

obtain the placeholder value from the proxy computing device.

7. The computing device of claim 6 , wherein to obtain the placeholder value, the programming instructions are further structured to cause the processor to:

establish a proxy session with the proxy computing device; and

receive the placeholder value from the proxy computing device.

8. The computing device of claim 1 , wherein to replace the placeholder in the first modified version of the code component with the placeholder value, the programming instructions are further structured to cause the processor to:

execute, by the embedding function, a call to the code rewriting function, the call comprising the first modified component as an argument thereof.

9. The computing device of claim 1 , wherein the programming instructions are further structured to cause the processor to:

store the embedding function and the code rewriting function in memory accessible to the computing device;

receive a modified version of a second resource from the proxy computing device, the modified version of the second resource comprising a prompt to access the embedding function.

10. A method performed by a client-side proxy service executing on a computing device comprising:

establishing a proxy session with a proxy-side proxy service executing on a proxy computing device;

receiving a placeholder value from the proxy-side proxy service, the placeholder value indicating an authentication credential is verified;

storing the placeholder value in memory accessible to the client-side proxy service;

detecting an event associated with an embedding function of the client-side proxy service and a code component of a resource;

generating, by the embedding function, a first modified version of the code component comprising a placeholder;

replacing, by a code rewriting function of the client-side proxy service, the placeholder with the stored placeholder value, resulting in a second modified version of the code component.

11. The method of claim 10 , wherein:

the resource comprises a web page;

the method further comprises presenting the web page in a browser executed by the computing device; and

said detecting the event comprises detecting the event in the web page.

12. The method of claim 10 , wherein the embedding function is stored in memory accessible to the client-side proxy service and the method further comprises:

receiving the resource from the proxy-side proxy service, the resource comprising the code component and a reference to the embedding function.

13. The method of claim 12 , further comprising:

accessing, based on the reference, the embedding function stored in the memory accessible to the client-side proxy service.

14. The method of claim 10 , wherein said replacing the placeholder with the stored placeholder value comprises:

executing, by the embedding function, a call to the code rewriting function, the call comprising the first modified component as an argument thereof.

15. A computer-readable storage medium having programming instructions encoded thereon that are executable by a processor circuit of a computing device to perform a method, the method comprising:

sending a request for a resource to a proxy computing device;

receiving, from the proxy computing device, a modified version of the resource, the modified version of the resource comprising an embedding function and a code rewriting function not included in the resource;

detecting an event in the resource associated with the embedding function and a code component;

inserting, by the embedding function, a placeholder in the code component, resulting in a first modified version of the code component;

verifying an authentication credential;

determining a placeholder value indicating the authentication credential is verified;

replacing, by the code rewriting function, the placeholder in the first modified version of the code component with the placeholder value, resulting in a second modified version of the code component.

16. The computer-readable storage medium of claim 15 , wherein the first resource comprises a web page, the modified version of the first resource comprises a modified version of the web page, and the method further comprises:

presenting the modified version of the web page in a browser executed by the computing device.

17. The computer-readable storage medium of claim 15 , wherein said determining the placeholder value comprises:

obtaining the placeholder value from the proxy computing device.

18. The computer-readable storage medium of claim 17 , wherein said obtaining the placeholder value comprises:

establishing a proxy session with the proxy computing device; and

receiving the placeholder value from the proxy computing device.

19. The computer-readable storage medium of claim 15 , wherein said replacing the placeholder in the first modified version of the code component with the placeholder value comprises:

executing, by the embedding function, a call to the code rewriting function, the call comprising the first modified component as an argument thereof.

20. The computer-readable storage medium of claim 15 , wherein the method further comprises:

storing embedding function in memory accessible to the processor circuit;

receiving another resource from the proxy computing device, the another resource comprising a reference to the embedding function; and

accessing, based on the reference, the embedding function stored in the memory accessible to the processor circuit.
