Abstract

A system, method and computer-readable medium for client-side cache management are provided. A client request for content is returned that includes executable code for generating a request for preload information. Based on processing the executable code, a client computing device requests preload information from a content delivery service provider. The content delivery service provider provides an identification of content based on resource requests previously served by the content delivery service provider. The client computing device processes the preload information and generates and obtains identified resources for maintenance in a client computing device memory, such as cache.

Claims

1. A computer-implemented method for processing content at a client computing device, the method comprising:

obtaining a set of content for processing on the client computing device, wherein the set of content includes executable code for causing the client computing device to generate a request to an identified service provider for a preload content list;

generating, at the client computing device, a request for the preload content list responsive to the execution of the executable code;

obtaining, from the identified service provider, the requested preload content list, wherein resources identified in the requested preload content list are unrelated at least in part to the set of content;

filtering, at the client computing device, the requested preload content list to identify a subset of resources from the requested preload content list; and

generating, at the client computing device, a request for preloading one or more of the subset of resources identified in the filtered preload content list at the client computing device;

wherein the method is implemented by the client computing device configured with specific executable instructions.

2. The computer-implemented method as recited in claim 1 further comprising:

obtaining the one or more of the subset of resources from the filtered preload content list; and

maintaining the one or more of the subset of resources for subsequent use.

3. The computer-implemented method as recited in claim 1, wherein the executable code includes code for identifying additional information associated with the client computing device and wherein the request for the preload content list includes the additional information.

4. The computer-implemented method as recited in claim 3, wherein the requested preload content list is associated with the additional information.

5. The computer-implemented method as recited in claim 1, wherein the resources identified in the requested preload content list include resources from previous content requests serviced by one or more cache components of the identified service provider.

6. The computer-implemented method as recited in claim 1, wherein the requested preload content list is filtered by the type or size of content.

7. The computer-implemented method as recited in claim 1, wherein the executable code further comprises executable instructions for processing the filtered preload content list at the client computing device.

8. The computer-implemented method as recited in claim 7, wherein the executable instructions for processing the filtered preload content list at the client computing device comprise instructions for managing storage controls at the client computing device for maintaining content both identified in the filtered preload content list and already stored at the client computing device.

9. A computer-implemented method for processing content at a service provider, the method comprising:

under control of one or more computing devices associated with the service provider and configured with specific executable instructions,

obtaining a request, from a client computing device, for a resource and a preload content list;

determining a set of content for identification in the requested preload content list, wherein at least a portion of the set of content identified in the requested preload content list is unrelated to the requested resource;

filtering the determined set of content based on additional information provided by the client computing device to identify a filtered preload content list; and

causing transmission of the filtered preload content list to the client computing device.

10. The computer-implemented method as recited in claim 9 further comprising obtaining the additional information provided by the client computing device with the request for the preload content list, wherein the set of content identified in the filtered preload content list is determined based on the additional information.

11. The computer-implemented method as recited in claim 10, wherein the additional information is behavioral information corresponding to the client computing device.

12. The computer-implemented method as recited in claim 9, wherein determining the set of content for identification in the requested preload content list further comprises determining the set of content for identification in the requested preload content list based on previously requested content provided by one or more cache components of the service provider.

13. The computer-implemented method as recited in claim 9, wherein determining the set of content for identification in the requested preload content list includes determining the set of content for identification in the requested preload content list based on previous content requests from a class associated with a set of client computing devices.

14. The computer-implemented method as recited in claim 9, wherein determining the set of content for identification in the requested preload content list includes determining the set of content for identification in the requested preload content list based on previous content requests from a class associated with the client computing device.

15. The computer-implemented method as recited in claim 9 further comprising obtaining, at the service provider, a request from the client computing device to preload content identified on the filtered preload content list at the client computing device.

16. A system comprising:

a client computing device having specific executable instructions stored in an associated memory and operative to;

obtain a set of content for processing on the client computing device, wherein the set of content includes executable code for causing the client computing device to generate a request to an identified service provider for a preload content list;

generate, at the client computing device, a request for the preload content list responsive to the execution of the executable code;

obtain, from the identified service provider, the requested preload content list, wherein resources identified in the requested preload content list are unrelated at least in part to the set of content;

filter, at the client computing device, the requested preload content list to identify a subset of resources from the requested preload content list; and

generate, at the client computing device, a request for preloading one or more of the subset of resources identified in the filtered preload content list at the client computing device.

17. The system as recited in claim 16 further comprising:

obtaining the one or more of the subset of resources from the filtered preload content list; and

maintaining the one or more of the subset of resources for subsequent use.

18. The system as recited in claim 16, wherein the executable code includes code for identifying additional information associated with the client computing device and wherein the request for the preload content list includes the additional information.

19. The system as recited in claim 16, wherein the resources identified in the requested preload content list include resources from previous content requests serviced by one or more cache components of the identified service provider.

20. A system comprising:

a service provider computing device having specific executable instructions stored in an associated memory and operative to;

obtain a request, from a client computing device, for a resource and a preload content list;

determine a set of content for identification in the requested preload content list, wherein at least a portion of the set of content identified in the requested preload content list is unrelated to the requested resource;

filter the determined set of content based on additional information provided by the client computing device to identify a filtered preload content list; and

cause transmission of the filtered preload content list to the client computing device.

21. The system as recited in claim 20, wherein the service provider computing device is further operative to obtain the additional information provided by the client computing device with the request for the preload content list, wherein the set of content identified in the filtered preload content list is determined based on the additional information.

22. The system as recited in claim 20, wherein determining the set of content for identification in the requested preload content list further comprises determining the set of content for identification in the requested preload content list based on previously requested content provided by one or more cache components of the service provider.
