Long: http3-direct Tags: Versions Protocols: HTTP Added: 7.66.0 Mutexed: http1.1 http1.0 http2 http2-prior-knowledge Requires: HTTP/3 Help: Use HTTP v3 --- WARNING: this option is experiemental. Do not use in production. Tells curl to use HTTP version 3 directly to the host and port number used in the URL. A normal HTTP/3 transaction will be done to a host and then get redirected via Alt-SVc, but this option allows a user to circumvent that when you know that the target speaks HTTP/3 on the given host and port.
