Expand description

Ensure an HTTP/1.x request carries a Host header.

HTTP/1 carries the routing authority in the Host header, whereas HTTP/2 and HTTP/3 carry it in the :authority pseudo-header (the URI). The Host header is derived from the request authority when missing. Used both when downgrading a request to HTTP/1 and as a general send-time backstop.
