摘要： A method and on-demand computing system for hierarchical caching of content in an on-demand computing device. The method receives, at the on-demand computing device, a request to send media content to a playback device, where the media content is stored in a media library of a content server. The method retrieves the media content from a hierarchical cache for the on-demand computing device, and sends the media content to the playback device. The hierarchical cache includes a first cache, a second cache, and the content library, where the first cache has a length based on an age of the second cache.
