Contributions summary:Josiah primarily contributed to the Envoy cache filter, focusing on improving and refactoring cache-related logic. Their work involved registering custom headers, creating a CachePolicy interface to allow for customized cache behavior, and refining the "vary" logic for cache key generation. Furthermore, they reorganized the code by separating concerns, such as moving range logic utilities into a dedicated module. The user also added FilterState to the cache filter to allow other filters to retrieve cache status.
