Hello,

 Is there any way, per currently-published standards, to upgrade a TLS connection from HTTP/1 to H2 based on its URL? e.g.:

https://example.com/http1   <-- served via HTTP/1

https://example.com/http2   <-- served via HTTP/3

 This is possible with non-TLS via normal HTTP upgrades but doesn’t appear to be possible via the ALPN approach mandated for TLS-secured HTTP/2 connections. It seems strange that there would be no way to do over TLS what’s easy to do in plain text. What am I missing?

 Thank you!
