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.

Persistent edge state of end user devices at network nodes

Systems, methods, apparatus, and software for transitional caching in content delivery networks includes edge cache nodes configured to receive and reply to content requests. Content can be cached in edge cache nodes before receiving user requests or retrieved from an origin server. A transitional cache node array is configured to receive content requests from edge cache nodes and to receive origin content from edge cache nodes and/or origin servers, as well as to modify origin content to generate modified content. Modified content can include re-written origin content (e.g., translations), transcoded data (e.g., video), compressed or otherwise adjusted data (e.g., images), and transformed files (e.g., CSS and JavaScript files), among others. In addition to assisting with original and modified content flow to end users, transitional caching also can assist in threat detection and mitigation within a CDN, helping to protect the network, origin servers and the like.

Content delivery network transitional caching

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 properties related to the end user device based at least on the content requests, and executing a per-user function in the cache node for the end user device based at least on the properties related to the end user device.

Execution of per-user functions at cache nodes

Disclosed herein are methods, systems, and software for bypassing a domain name system. In one example, a method of operating a user communication device includes receiving a user instruction requesting content within a user application of the user communication device. The method further provides, in response to the user instruction, processing at least a domain name system bypass data structure on the user communication device to identify a network address for retrieving the content. The method further includes, requesting the content from a content node using the network address.

Domain name system bypass in user applications

Persistent edge state of end user devices at cache nodes

Systems, methods, and software for operating a content node are provided herein. In one example, a method of operating a content node is presented. The method includes receiving a characteristic of an end user device, and configuring one or more transmission control protocol (TCP) parameter for communications with the end user device based on at least the characteristic of the end user device. The method also includes transferring the communications using the one or more TCP parameters for delivery to the end user device.
