Abstract
A method and system for reducing the number of conditional requests for network content to a server by maintaining state for selected URIs in a local cache indicative of a confidence level that the files are unchanged. When a request for content is received that corresponds to such a URI in the cache, a synchronization time is determined based on a confidence level for that URI. If the synchronization time is achieved, a conditional request is sent to the server, otherwise the URI data is returned from the cache to respond to the request. Synchronization intervals for such files may be increased as the likelihood that the item is unmodified increases. URIs may need to be of a certain content type and required to pass a confidence test before being selected for automatic synchronization.
