Systems and techniques for edge cache static asset optimization are described herein. A set of tracking instructions may be generated for execution at an edge cache server of the content delivery system. A static asset may be identified that is included in a webpage delivery session. A type may be determined for the static asset. The static asset may be grouped with a set of other static assets based on the type. The webpage request may be processed by processing the static asset. The set of tracking instructions may be transmitted to an edge cache server for storage in an edge cache of an edge network.
