Patent attributes
A method, system, an apparatus are directed towards selectively prefetching content over a network. A request for a content object is received. The content object may comprise a link to another content object. A cachability measure for the link may be determined based on whether a plurality of previous requests for the link returned the other content object, an annotation in a link map, a probability of traversing the link, a network metric, or the like. A prefetchability measure for the link may be determined based on the cachability measure and/or another factor relating to the link. The other factor may be an annotation of the link indicating that caching the other content object will cause a related object to be uncachable. Based on the prefetchability measure, the other content object is selectively prefetched for subsequent provisioning and/or display.
