摘要:
A user device includes a display screen and one or more processors. The one or more processors are configured to preload one or more user applications in a background mode, in which User Interface (UI) displays associated with preloaded user applications are invisible on the display screen, to detect a launch of a UI display that is associated with a given preloaded user application, to assess whether the UI display is a preload-initiated UI display that is invoked due to preloading of the given user application, or whether the UI display is a user-initiated UI display that is invoked due to an action by the user, to handle the UI display using a first handling scheme if the UI display is assessed to be a preload-initiated UI display, and, if the UI display is assessed to be a user-initiated UI display, to handle the UI display using a second handling scheme, different from the first handling scheme.
摘要:
A method includes issuing, by an application running in a user device, a request to fetch over a network content that includes multiple content items. The request is received by a software agent running in the user device and, in response to the request, a chain of fetch operations is executed for fetching the requested content. Each of the fetch operations in the chain includes (i) receiving from the application an identification of one or more additional content items identified by the application within a content item fetched in a preceding fetch operation in the chain, (ii) evaluating a criterion, and (iii) deciding, depending on the criterion, whether or not to fetch the one or more additional content items.
摘要:
A method for content delivery includes selecting one or more time intervals. During each time interval among the selected time intervals, given content is prefetched from a content source to a communication terminal using a guaranteed prefetching mode, by continuously tracking the given content on the content source, so as to detect changes to the given content as they occur during the selected time interval, and maintaining the communication terminal continuously synchronized with the content source with respect to the given content, throughout the selected time interval, notwithstanding the changes that occur during the selected time interval, by continuously prefetching at least part of the given content from the content source to the communication terminal. Outside of the one or more selected time intervals, the given content is prefetched using a best-effort prefetching mode, by tracking the given content less frequently than the guaranteed prefetching mode.
摘要:
A method includes determining available prefetch updates for a user device. Prefetch notifications, which notify the user device of the available prefetch updates, are sent to the user device. At least a portion of the prefetch updates is embedded in one or more of the prefetch notifications.
摘要:
A method for content delivery includes defining a guaranteed prefetching mode, in which content is continuously prefetched from a content source to a communication terminal of a user so as to maintain the communication terminal synchronized with the content source. One or more time-of-day intervals, during which the user is expected to access given content, are identified. During the identified time-of-day intervals, the given content is prefetched from the content source to the communication terminal using the guaranteed prefetching mode.
摘要:
A method includes caching content items in a cache memory of a communication terminal connected to a communication network. A content item, which is cached in the cache memory, is presented to a user of the communication terminal. An extent of freshness of the cached content item presented to the user is assessed. Presentation of the cached content item is conditionally modified depending on the assessed extent of freshness.
摘要:
Apparatus and methods are described, including a method for use with a first content delivery network (CDN) and a second CDN that are used by a content source. A processor is used to identify that a device is requesting an exchange of content with the content source, identify a property of the requested exchange of content, and based on the property, select one of the first CDN and the second CDN. Subsequently, content is exchanged between the device and the selected CDN. Other embodiments are also described.

摘要:
A method includes, in a user device (24) that is configured to communicate over a network (32), preloading an application (26) in a background mode in which content presented by the application is hidden from a user of tire user device. At least part of the content presented by the application is pre-rendered in an off-line pre-render mode in which fetching of content over the network to the user device is not permitted. In response to an action by the user that requests to access the application, a switch is made to presenting at least the pre-rendered content to the user in a foreground mode.
