See (B) from brave/brave-browser#22927

Current state

Public gateways inline DNSLink names into a single label if X-Forwarded-Proto: https is present (see docs)

• https://dweb.link/ipns/en.wikipedia-on-ipfs.org → redirect → https://en-wikipedia--on--ipfs-org.ipns.dweb.link/wiki/

Localhost gateway does not do that, it keeps the subdomains as they are:

• http://localhost:48080/ipns/en.wikipedia-on-ipfs.org → redirect → http://en.wikipedia-on-ipfs.org.ipns.localhost:48080/wiki/

Requested enhancement

Brave team asked for a configuration flag that enables DNSLink name inlining into a single DNS label without switching protocol to https (brave/brave-browser#22927).

Proposed design

Add new optional Flag to Gateway.PublicGateways named UseInlinedDNSLink (disabled by default).
