Tag-based cache purges are something I would love to see in ATS. I think doing it correctly would require a complete rejiggering of the cache storage though, and that&#x27;s not something to be undertaken lightly.<p>Storing externally in redis (for ledge) seems like the wrong approach to me. Better to store metadata externally and generate the purge URLs based on that. It&#x27;s not ideal, but it&#x27;s the best option I&#x27;ve come up with.
