Abstract:
A tiered caching system (e.g., in an overlay network such as CDN) wherein SWR at an edge server therein is automatically set (preferably based on request rate), while SWR at a parent server therein has its SWR set at or near 0. Collectively, these SWR settings provide for a self-adjusting tiered caching system that optimizes both end user performance and the origin traffic offload

Claim (Index 1):
A system associated with an origin server at which content to be delivered to a set of client machines is published, comprising:\n an overlay network comprising a computing machine having a hardware processor, and computer memory; a server process executing in the hardware processor; the server process configured to enforce a stale-while-revalidate (SWR) cache-control whereby the server process is enabled to return a stale response in response to a request while attempting to revalidate the request in a background action; the server process configured to compute and enforce an SWR cache-control value set to a first SWR value, wherein the first value is a function of rate of requests from the set of client machines received at the server process; wherein the first SWR value is SWR (% of TTL)=100/(TTL*R), wherein TTL refers to a Time-To-Live (TTL) of the content and R is the rate of requests; wherein enforcing the first SWR value improves an operation of the overlay network by reducing internal traffic being the edge server process and the origin server process.
