There was a problem hiding this comment.
Lgtm, we will likely refine cache-control across all response types, but this is useful fix of a hot path (dir listings on /ipfs should benefit from wider cache window).
Related spec clarification in ipfs/specs#480
Digression:
max-agebased on TTL for/ipns/{dnslink}is unrelated to this fix, but we may want to fix it sooner than later, as Gateway: Cache-Control, max-age=ttl, ETag for /ipns requests #329 (comment) impacts directory listings, and that is why this PR is limited to dir listings on/ipfs.- We are not married to the
stale-while-revalidatevalue on IPNS, could adjust if needed (mutable conformance tests only care aboutmax-age), but 1 month sounds more robust than a few days or a week, the intention is to avoid link rot, if http cache supports such wide window.
