https://staltz.com/.well-known/dat redirects to https://staltz.com/dat which returns a 200 status code and a Dat-DNS file in the expected format. dat-dns treats the redirect as a failure so @staltz’s homepage won’t load in Beaker, however.
dat-dns should follow same-origin (same scheme, domain, and port) redirects. Cross-origin redirects may have security implications. Same-origin redirects should be safe, however.
