    Abstract: A device is operable in a content delivery network (CDN). The device has a cache server mechanism constructed and adapted to: upon joining the CDN, obtain global configuration data from a control core of the CDN; and, having joined the CDN, obtain updated global configuration data, if needed; and obtain customer configuration information associated with at least one customer of the CDN. The device serves a particular resource associated with a particular customer of the CDN in accordance with (i) the global configuration data, and (ii) customer configuration information obtained in and associated with the particular customer.

    Abstract translation: 设备可在内容传送网络（CDN）中操作。 该设备具有缓存服务器机制，其构造并适于：在加入CDN时，从CDN的控制核心获取全局配置数据; 加入CDN后，如果需要，获取更新的全局配置数据; 并获得与CDN的至少一个客户相关联的客户配置信息。 根据（i）全局配置数据，以及（ii）在特定客户中获得并与特定客户相关联的客户配置信息，该设备服务与CDN的特定客户相关联的特定资源。

    Abstract: A computer-implemented method, operable with a content delivery network (CDN) uses late binding of caching policies; by a caching node in the CDN, in response to a request for content, determining if the content is cached locally. When it is determined that said content is cached locally, then: determining a current cache policy associated with the content; and then determining, based on said current cache policy associated with the content, whether it is acceptable to serve the content that is cached locally; based on said determining, when it is not acceptable to serve the content that is cached locally, obtaining a new version of the content and then serving the new version of the content, otherwise when it is acceptable to serve the content that is cached locally, serving the content that is cached locally.

    Abstract: Examples described herein relate to systems and methods for containing a faulty stimulus. A computer-implemented method may include listing in a suspect list every received stimulus including the faulty stimulus, and implicitly testing the stimuli by respectively acting upon those stimuli by a software application. Responsive to successfully acting upon each of the stimuli besides the faulty stimulus, each non-faulty stimulus is deleted from the suspect list and, responsive to such deletion, made available to a downstream node. Responsive to acting upon the faulty stimulus, the software application crashes which leaves the faulty stimulus listed in the suspect list. The software application then restarts and deems the faulty stimulus as being faulty based upon the faulty stimulus still being listed in the suspect list after the restart.

    Abstract: A method for registering a handler in a configured sequence of handlers includes: receiving, by a processor and memory implementing a sequencer infrastructure, a configuration script defining a sequence including one or more handler identifiers and corresponding one or more handler arguments; invoking a handler initialization entry point for a handler corresponding to a handler identifier, the invoking the handler initialization entry point including: selecting, based on the corresponding one or more handler arguments, a handler type from among two or more of: a configured instance of the handler; a configured alternate handler different from the handler; an alternate sequence of handlers; an expression; and a no-op handler; and initializing a configured handler based on the handler type selected and the corresponding one or more handler arguments; and adding the configured handler to a configured sequence of handlers.

    Abstract: Examples described herein relate to apparatuses and methods for managing caching for a content delivery system, which may include receiving a content request indicating that the caching agent is requesting content data for a client, filling the content data in a first cache storage of the business logic agent, providing the cached content data to the caching agent, and while a second cache storage of the caching agent is being filled with the content data, maintaining the cached content data in response to receiving additional content requests from the caching agent. The additional content requests may indicate that the caching agent is requesting the same content data for additional clients.
