Abstract

The present invention relates to methods, apparatus, and systems for implementing cache cycling. The system includes a gateway in communication with a satellite. The gateway includes a gateway accelerator module which further includes a proxy server. The proxy server is configured to receive the request for the new copy of the requested content and forward the request. Furthermore, the system includes a content provider in communication with the gateway. The content provider is configured to receive the content request and transmit the new copy of the requested content to the gateway. The gateway is configured to transmit the new copy of the content to the subscriber terminal via the satellite, and wherein the subscriber terminal is further configured to replace the requested content stored in the terminal cache module with the new copy of the requested content. The content stored in the terminal cache module is updated for subsequent requests.

Claims

1. A system for implementing cache cycling, the system comprising:

a client configured to generate a content request;

a subscriber terminal including a terminal cache module and a terminal accelerator module which includes a proxy client, wherein the proxy client is configured to intercept the content request, access the terminal cache module, and determine that the requested content is stored in the terminal cache module, issue a request for a new copy of the requested content, and transmit the requested content stored in the terminal cache module to the client;

a satellite in communication with the subscriber terminal, the satellite configured to transmit data;

a gateway in communication with the satellite, the gateway including a gateway accelerator module which includes a proxy server, the proxy server configured to receive the request for the new copy of the requested content and forward the request; and

a content provider in communication with the gateway, the content provider configured to receive the content request and transmit the new copy of the requested content to the gateway,

wherein the gateway is configured to transmit the new copy of the content to the subscriber terminal via the satellite; and

wherein the subscriber terminal is further configured to replace the requested content stored in the terminal cache module with the new copy of the requested content, such that the content stored in the terminal cache module is updated for subsequent requests.

2. A system for implementing cache cycling as in claim 1, wherein the content request includes a URL string for locating the requested content.

3. A system for implementing cache cycling as in claim 2, wherein the URL string comprises a masked URL string.

4. A system for implementing cache cycling as in claim 3, wherein a masked URL string comprise at least a portion of the URL string being randomly generated, and the masked URL string removed and/or replaces the at least a random portion of the URL string.

5. A system for implementing cache cycling as in claim 2, wherein the terminal accelerator module is further configured to determine portions of the URL string that are randomly generated for each request according to a particular random generation policy.

6. A system for implementing cache cycling as in claim 5, wherein the terminal accelerator module is further configured to generate a random string according to the random generation policy and insert the random string into the URL string in order to request the new copy of the requested content.

7. A system for implementing cache cycling as in claim 1, wherein the requested content comprises advertising content.

8. A system for implementing cache cycling as in claim 7, wherein the request for the advertising content includes cookies, client targeting parameters, and localization information associated with the request.

10. A system for implementing cache cycling as in claim 1, wherein the satellite comprises a bent pipe satellite.

11. A system for implementing cache cycling as in claim 1, wherein the new copy of the requested content comprises a fresh copy of the requested content.

12. A system for implementing cache cycling as in claim 1, wherein the client is further configured to render the requested content.

13. A system for implementing cache cycling as in claim 1, wherein the terminal cache module is further configured to stored the new copy of the requested content.

9. A system for implementing cache cycling as in claim 9, wherein the advertising content includes advertising accounting requirements, and as such, the requesting of the new copy of the requested content maintains the advertising accounting requirements.

14. A method of implementing cache cycling, the method comprising:

generating, at a client, a content request;

intercepting, at a subscriber terminal, the content request;

accessing a terminal cache module to determine that the requested content is stored in the terminal cache module;

issuing a request for a new copy of the requested content;

transmitting the requested content stored in the terminal cache module to the client;

receiving, at a gateway, the request for the new copy of the requested content;

receiving, at a content provider, the content request and transmitting the new copy of the requested content to the gateway;

transmitting the new copy of the content to the subscriber terminal; and

replacing the requested content stored in the terminal cache module with the new copy of the requested content, such that the content stored in the terminal cache module is updated for subsequent requests.

15. A method of implementing cache cycling as in claim 14, further comprising rendering the requested content in the client'"'"'s browser.

16. A method of implementing cache cycling as in claim 14, wherein the content request includes a URL string for locating the requested content.

17. A method of implementing cache cycling as in claim 14, further comprising determining portions of the URL string that are randomly generated for each request according to a particular random generation policy.

18. A method of implementing cache cycling as in claim 17, further comprising generating a random string according to the random generation policy.

19. A method of implementing cache cycling as in claim 18, further comprising inserting the random string into the URL string in order to request the new copy of the requested content.

20. A method of implementing cache cycling as in claim 14, wherein the rested content comprises an HTTP request.

21. A machine-readable medium having sets of instructions which, when executed by a machine, cause the machine to:

generate, at a client, a content request;

intercept, at a subscriber terminal, the content request;

access a terminal cache module to determine that the requested content is stored in the terminal cache module;

issue a request for a new copy of the requested content;

transmit the requested content stored in the terminal cache module to the client;

receive, at a gateway, the request for the new copy of the requested content;

receive, at a content provider, the content request and transmitting the new copy of the requested content to the gateway;

transmit the new copy of the content to the subscriber terminal; and

replace the requested content stored in the terminal cache module with the new copy of the requested content, such that the content stored in the terminal cache module is updated for subsequent requests.

22. The machine-readable medium as in claim 21, wherein the sets of instructions, when further executed by the machine, cause the machine to store the new copy of the requested content at the terminal cache module.
