Abstract

See full text

A method includes altering a request interval threshold when a cache-hit ratio falling below a target, receiving a request for content, providing the content when the content is in the cache, when the content is not in the cache and the time since a previous request for the content is less than the request interval threshold, retrieving and storing the content, and providing the content to the client, when the elapsed time is greater than the request interval threshold, and when another elapsed time since another previous request for the content is less than another request interval threshold, retrieving and storing the content, and providing the content to the client, and when the other elapsed time is greater than the other request interval threshold, rerouting the request to the content server without caching the content.
