CACHING IN A CONTENT DELIVERY FRAMEWORK
First Claim
1. A computer-implemented method, operable with a content delivery network (CDN), the method comprising, by a node in the CDN:
- (A) in response to a request for content, determining if the content is cached locally;
(B) when it is determined that said content is cached locally, then;
(B)(1) determining a current cache policy associated with the content; and
then(B)(2) determining, based on said current cache policy associated with the content, whether it is acceptable to serve the content that is cached locally;
(B)(3) based on said determining in (B)(2),(i) when it is not acceptable to serve the content that is cached locally, obtaining a new version of the content and then serving the new version of the content, and(ii) when it is acceptable to serve the content that is cached locally, serving the content that is cached locally.
