Just wanted to follow up on one point from yesterday’s EoH presentation in REGEXT. When comparing EoH with DoH, it was noted that both use GET and POST. But there is one important distinction when it comes to BCP 56. DoH correctly falls back to POST if an equivalent GET query gets too large, per BCP 56 (4th para in [1]). In contrast, EoH seems to overload the POST use for PUT and DELETE scenarios, violating BCP 56. IMHO, it does not help to compare EoH with DoH. Guess that’s why the HTTPDIR review [2] recommended HTTP CONNECT instead to avoid the BCP 56 violation.

I thing you missed that DoH allows for virtually any DNS packet, also UPDATE (which makes for Add/Update/Delete) - which would be still GET/POST http requests.

Kind Regards,
Pawel
