摘要： Requests for content can be received from clients and forwarded to servers, and responses to the requests can be received from the servers and forwarded to the clients. A health model can also be maintained. The health model can be based on information in the responses and possibly also on information in the requests, and the health model can indicate the health of the servers in responding to different types of requests. The health model may differentiate between health in responding to requests with different features in URLs of the requests, such as different namespaces and/or different extensions.

摘要： A caching system segments content into multiple, individually cacheable chunks cached by a cache server that caches partial content and serves byte range requests with low latency and fewer duplicate requests to an origin server. The system receives a request from a client for a byte range of a content resource. The system determines the chunks overlapped by the specified byte range and sends a byte range request to the origin server for the overlapped chunks not already stored in a cache. The system stores the bytes of received responses as chunks in the cache and responds to the received request using the chunks stored in the cache. The system serves subsequent requests that overlap with previously requested ranges of bytes from the already retrieved chunks in the cache and makes requests to the origin server only for those chunks that a client has not previously requested.

摘要： An intelligent caching system is described herein that intelligently consolidates the name-value pairs in content requests containing query strings so that only substantially non-redundant responses are cached, thereby saving cache proxy resources. The intelligent caching system determines which name-value pairs in the query string can affect the redundancy of the content response and which name-value pairs can be ignored. The intelligent caching system organically builds the list of relevant name-value pairs by relying on a custom response header or other indication from the content server. Thus, the intelligent caching system results in fewer requests to the content server as well as fewer objects in the cache.

摘要： A selective pre-caching system reduces the amount of content cached at cache proxies by limiting the cached content to that content that a particular cache proxy is responsible for caching. This can substantially reduce the content stored on each cache proxy and reduces the amount of resources consumed for pre-caching in preparation for a particular event. The cache proxy receives a list of content items that and an indication of the topology of the cache network. The cache proxy uses the received topology to determine the content items in the received list of content items that the cache proxy is responsible for caching. The cache proxy then retrieves the determined content items so that they are available in the cache before client requests are received.

摘要翻译： 选择性预缓存系统通过将缓存内容限制为特定缓存代理负责缓存的内容来减少缓存代理缓存的内容量。 这可以显着减少存储在每个缓存代理上的内容，并且减少为预先缓存而消耗的资源量，以准备特定事件。 高速缓存代理接收内容项的列表以及高速缓存网络拓扑的指示。 缓存代理使用接收到的拓扑来确定缓存代理负责缓存的内容项的接收列表中的内容项。 缓存代理然后检索确定的内容项，使得它们在接收到客户端请求之前在高速缓存中可用。
