By the Host header. I've been looking into this issue tonight and
think I have the answers (but it's really late, so I'll save the gory
details for tomorrow). In brief: typically, req.hostname is set from
the Host header and, in fact, when I telnet to apache and issue a GET
by hand, if I don't send the Host header, apache barfs with a 400, Bad
Request, response. (apache 2.0.54, debian testing)
It will only do that if you claim to be a HTTP/1.1 client. If you send
GET / HTTP/1.0
it will not complain about the host header. Sending:
GET / HTTP/1.1
will get you a 400 response, because you MUST supply it (says RFC 2068,
and whatever superseded that one). There is more you must do to be able
to call yourself HTTP/1.1 by the way, such as keep-alive connections and
chunked encoding.
