If the client does not send the "Host" header, and you have an ancient
HTTP/1.0 proxy that does not generate the "Host" header on its own, then
the request will not have a "Host" header when it reaches the server. As
the server might depend on the presence of the Host header to serve the
request, it's better to send the "Host" header even if the information
in the header is, strictly speaking, redundant in the specific case. If
that clarifies the intended meaning, how would you phrase that?
