摘要： Aspects of the present disclosure involve systems, methods, computer program products, and the like, for a content delivery network (CDN) architecture utilizing one or more proxy cache devices between a requesting device and an edge cluster of the CDN. The proxy cache device is a relatively high speed device compared to various possible devices making up one or more edge clusters. Thus, if the proxy has cached the requested content, it is capable of directly servicing the client content request at a faster rate than providing the content from the edge cluster. Otherwise, the proxy cache may request the content from an edge cluster and store the content for quick retrieval in response to additional requests for the content. In one embodiment, the proxy cache may perform an analysis of the request or a series of requests to determine if the content is cached at the proxy cache device.
