Abstract
The presentation of content items within a hosting item is typically performed by on-demand retrieval of the content item from a content server. However, on-demand retrieval may impose an undesirable delay in the presentation of the content; may spontaneously alter the layout of the hosting item; and/or may involve an expedient but unsophisticated selection among the content items of a content store (e.g., random selection), resulting in the presentation of irrelevant and/or redundant content. Instead, a device may prefetch content items into a content cache, such that when a user later requests to view a hosting item, the device may insert a content item selected from the content cache. The device may also notify the content server when a content item has been presented to the user; by marking the content item as such, the content server may provide additional, fresh content for the device content cache.
