Component: documentation → http/3
Resolution: → invalid
Status: new → closed

The http3_hq directive switches HTTP/3 to a special application protocol used mainly in QUIC protocol interoperability testing and negotiated with ALPN token "hq-interop". As such, it's not for use with conventional HTTP/3 clients.
