摘要： To serve content through a content delivery network (CDN), the CDN must have some information about the identity, characteristics and state of its target objects. Such additional information is provided in the form of object metadata, which according to the invention can be located in the request string itself, in the response headers from the origin server, in a metadata configuration file distributed to CDN servers, or in a per-customer metadata configuration file. CDN content servers execute a request identification and parsing process to locate object metadata and to handle the request in accordance therewith. Where different types of metadata exist for a particular object, metadata in a configuration file is overridden by metadata in a response header or request string, with metadata in the request string taking precedence.

摘要翻译： 为了通过内容传递网络（CDN）提供内容，CDN必须具有关于其目标对象的身份，特征和状态的一些信息。 这样的附加信息以对象元数据的形式提供，其根据本发明可以位于请求字符串本身，来自原始服务器的响应头部，分发到CDN服务器的元数据配置文件中， 客户元数据配置文件。 CDN内容服务器执行请求标识和解析过程以定位对象元数据并根据其处理请求。 在特定对象存在不同类型的元数据的情况下，配置文件中的元数据将在响应头或请求字符串中的元数据覆盖，请求字符串中的元数据优先。
