I believe the answer is “sort of”. If you accept the responsibility for doing all reads, and all writes, then yes. But if you expect to write to the cache, and then let ATS itself be able to serve it via an HTTP request, then I believe it’s no. What’s missing are an API to link the header object to the variants (if I recall). — Leif
