Provided is a content delivery method and architecture for ways to improve the caching of content at one or more content providing devices of a Content Delivery Network (CDN). In particular, systems and methods are disclosed that vary the requirements to store resources or content within a caching device using a dynamic popularity threshold. This popularity threshold may be varied based on a measured fullness of the storage capacity of the cache device. In another example, the dynamic popularity threshold may be further varied based on a cache pressure, which is an indication of how often the cache replaces stored items with new items. The adjustment to the popularity threshold for caching particular content at the caching device may thus be based on a number of requests for content received at the device to tune the caching procedure for a particular region of the CDN.

System and method for improvements to a content delivery network

Examples described herein relate to standardizing content requests and responses in a content delivery network (CDN). An edge node receives a control object including sets of instructions each implementing portions of a customer's business logic. The edge node may receive, from a client, a content request identifying a content item, and may apply a set of the instructions which causes the edge node to (i) determine whether any changes are needed for the benefit of a cache server and whether any changes are need for the benefit of an origin server, and (ii) generate a processed client request identifying the content item and including, if needed, any changes for the benefit of the cache server and the origin server. The edge node transmits the processed client request to the cache server, receives a response from the cache server, and transmits a processed client response to the client.
