Abstract

A method and system to determine whether a web page has been cached is provided. An example system comprises a cookie generator, a cookie distributor, and a cookie evaluator. The cookie distributor may be configured to provide the code to a client system, in response to a request for web content from the client system. A value of the code to be updated at the client system in response to the client system initiating a request for the web content. The cookie evaluator may be configured to compare a value of the code to the default value. The cached status detector may be configured to use a result of the comparing to determine a cached status of the web content, the cached status to indicate whether the web content has been cached by the client system.

Claims

1. A system comprising:

a cookie generator to;

create a code on the server system, and

set a value of the code to a default value;

a cookie distributor to provide the code to a client system, in response to a request for web content from the client system, a value of the code to be updated at the client system in response to the client system initiating a request for the web content;

a cookie evaluator to compare a value of the code to the default value; and

a cached status detector to use a result of the comparing to determine a cached status of the web content, the cached status to indicate whether the web content has been cached by the client system.

2. The system of claim 1, wherein the code is a web cookie.

3. The system of claim 1, further comprising:

a web content request detector to receive, from a client system, a request for the web content; and

a response generator to provide the requested web content to the client system together with a request to set the code at the client system to an updated value.

4. The system of claim 3, wherein the updated value is the default value.

5. The system of claim 3, further comprising an update module to update the default value to a new default value wherein the updated value is a new default value.

6. The system of claim 1, wherein the web content includes a third party content, the third party content is associated with an identifier, the identifier to be saved in the code.

7. The system of claim 6, comprising:

a web content request detector to receive, from a client system, a request for the web content; and

a response generator to provide the requested web content to the client system together with a request to erase the identifier from the code.

8. The system of claim 1, wherein the web content loaded status detector is to send to the client system a request to load the web content.

9. The system of claim 1, wherein the code evaluator is to:

determine that a value of the code matches the default value; and

conclude that the web content has not been cached by the client system.

10. The system of claim 1, wherein the code evaluator is to:

determine that a value of the code is distinct from the default value; and

conclude that the web content has been cached by the client system.

11. A method comprising:

creating a code on the server system;

setting a value of the code to a default value;

providing the code to a client system, in response to a request for web content from the client system, a value of the code to be updated at the client system in response to the client system initiating a request for the web content;

comparing a value of the code to the default value; and

using a result of the comparing to determine a cached status of the web content, the cached status to indicate whether the web content has been cached by the client system.

12. The method of claim 11, further comprising:

receiving a request for the web content; and

providing the web content to the client system.

13. The method of claim 11, wherein the updated value is the default value.

14. The method of claim 13, further comprising updating a value of the code on the server system to a new default value, wherein the updated value is the new default value.

15. The method of claim 11, wherein the web content includes a third party content, the third party content being associated with an identifier, the identifier to be saved in the code at the client system.

16. The method of claim 11, wherein the operation to determine a cached status of the web content comprises:

determining that a value of the code matches the default value; and

generating an indication that the web content has not been cached by the client system.

17. The method of claim 11, wherein the operation to determine a cached status of the web content comprises:

determining that a value of the code is distinct from the default value; and

generating an indication that the web content has cached by the client system.

18. The method of claim 11, wherein a value of the code to be updated at the client system by incrementally increasing the value of the code in response to the client system initiating a request for the web content.

19. The method of claim 11, wherein a value of the code to be updated at the client system by incrementally decreasing the value of the code in response to the client system initiating a request for the web content.

20. A machine-readable medium having instruction data to cause a machine to:

create a code on the server system;

set a value of the code to a default value;

provide the code to a client system, in response to a request for web content from the client system, a value of the code to be updated at the client system in response to the client system initiating a request for the web content;

compare a value of the code to the default value; and

use a result of the comparing to determine a cached status of the web content, the cached status to indicate whether the web content has been cached by the client system.
