Abstract
A server computer identifies a cached document and its associated cache update history in response to a request or in anticipation of a request from a client computer. The server computer analyzes the document's cache update history to determine if the cached document is de facto fresh. If the cached document is de facto fresh, the server computer then transmits the cached document to the client computer. Independently, the server computer also fetches an instance of the document from another source like a web host and updates the document's cache update history using the fetched instance of the document.
