Abstract
Before preloading a document to a client device, a server computer gets a client cache map associated with the client device. The client cache map has a matching entry for each document cached by the client device's cache. The server computer first checks if the document to be preloaded is already in the client device's cache by looking up the client cache map. If the document is cached, the server computer then checks whether the cached document's content is still fresh. As a result, the server computer preloads the document to the client device if the document is not cached or if the cached document's content is stale.
