I' m using a local domain(not a public one), and at the moment this is my Caddyfile {

    respond "Hello"

}

caloecla.com:2082 {

    tls internal

    respond "Hello sicuro"

}

Why are you stuck on this version?! It’s more than 2 years old! Upgrade to latest and it’ll be enabled by default.

i’m using this version because i’ m tryng to implement a QUIC attack related to this version in my local virtual machine, for a university project exam. In the paper the user used that particular version of Caddy Server, and i don’t know if with new version the vulnerability is still there(maybe yes because is a QUIC vulns, not a caddy one)

I see. Well, in that version, enabling QUIC/HTTP3 was done by adding experimental_http3 to the global options. For example, you can add it after the https_port 2082 line.
