@marten-seemann I'm not sure if that actually works.

Because how a token is embedded in an Initial packet depends on the actual version of the QUIC packet that the server is processing. Therefore, I think that the server needs to first consult the version number on the wire, then use that to determine where the token is to decrypt the initial salt contained in the token.

Or are you suggesting something different?
