Abstract: The distribution network comprising a plurality of caching nodes and wherein the web content had been statically identified as an uncacheable content and originated on an origin-server and wherein the method establishes a time to live, TTL, period value to said uncacheable content based on users requests and responds to said users requests by sending to at least to one CDN user said uncacheable content within said TTL period value. Each one of said plurality of caching nodes in said distribution network including a content caching manager and a pseudo-dynamic content TTL predictor and performing the following steps: a) contacting each one of said plurality of nodes with a centralized repository, in order to download the configuration file of a plurality of said CDN users. b) identifying, said content caching manager of each caching node, the uncacheable content as a pseudo-dynamic content; c) predicting, a pseudo-dynamic content TTL predictor of said caching node, said TTL period value in which the uncacheable content will not be modified; and d) caching, each one of said plurality of nodes, the uncacheable content during said predicted TTL period value. The system of the invention is arranged to implement the method of the invention.

Abstract translation: 所述分配网络包括多个高速缓存节点，并且其中所述网络内容已被静态地标识为不可缓存的内容并且起源于原始服务器，并且其中所述方法基于用户向所述不可缓存的内容建立生存时间，TTL，周期值 通过向所述TTL周期值内的至少一个CDN用户发送所述不可缓存的内容来请求并响应所述用户的请求。 所述分配网络中的所述多个高速缓存节点中的每一个包括内容缓存管理器和伪动态内容TTL预测器，并且执行以下步骤：a）将所述多个节点中的每一个与集中式存储库联系起来，以便下载 多个所述CDN用户的配置文件。 b）将每个高速缓存节点的所述内容缓存管理器识别为所述不可缓存的内容作为伪动态内容; c）预测所述缓存节点的伪动态内容TTL预测器，其中不可修改内容将不被修改的所述TTL周期值; 以及d）在所述预测的TTL周期值期间，高速缓存所述多个节点中的每一个，不可缓存的内容。 本发明的系统被设置为实现本发明的方法。
