Abstract

Systems, methods, apparatuses, and software for caching tracking elements of network content are provided herein. In one example, a method of operating a cache node of a content delivery network that caches content for delivery to end user devices is provided. The method includes receiving content requests from an end user device for content cached by the cache node and responsively providing the content for delivery to the end user device, processing the content requests to determine a edge state that corresponds to the end user device, transferring information related to the edge state for delivery to at least one other cache node of the content delivery network for handling of content requests received at the at least one other cache node.
