The web server can serve a page at this location or do an HTTP or client-side redirect. The location should be restricted to HTTPS, including any redirects. RFC5785 doesn’t mention scheme restrictions but hopefully we can work that out with the reviewers.

Hi John,

Scheme restrictions aren't an issue; a well-known URL can specify what scheme(s) it can be used with (as long as they're covered by well-known; currently the set is (http, https, ws, wss).

The other way to do this would be some form of metadata in the response -- either a header or something in HTML (probably a new link relation in both cases would cover it). That's more verbose, but also would allow more flexibility. Have you considered that? (Not saying it's better necessarily).

Cheers,
