Steps to reproduce

Edge’s HTTP cache uses heuristic freshness to cache some status codes, but not all where it is allowed by the specification.

In particular, 200 is stored with heuristic freshness, while others allowed by HTTP – 203, 204, 404, 405, 410, 414 and 501 – are not.

Safari caches all of these status codes using heuristic freshness.
