ExtendedConnectRequest class

An Extended CONNECT request (RFC 9220) used to bootstrap protocols such as WebTransport or WebSockets over HTTP/3.

In addition to the standard HTTP/3 pseudo-headers (:method, :scheme, :authority, :path), this request carries a :protocol pseudo-header that identifies the desired application protocol (e.g. "webtransport" or "websocket").

The :method is always "CONNECT".
