Abstract
To determine whether a request or an associated response is cached, the request may be received by a first server associated with a Content Delivery Network (CDN). Based on configuration data for the server, a header is generated based on characteristics of the request, indicating that a response associated with the request is able to be cached. A second server associated with generation of a response receives the request. In response to the header, the second server generates a caching determination based on configuration data and the characteristics of the request. When the first server receives the response and the caching determination, the response may be stored. Use of the second server to generate caching determinations eliminates the need to change the configuration of devices associated with the CDN while enabling requests from multiple CDN devices to be cached without requiring changes to be deployed to each device.
