Yeah, I found that a second after I send this mail myself... it's even
given as example in the doku. However. While the Apache PHP module
understands this, the Apache itsself does not. It always uses the first
configured Virtual Host even if another was requested.
I cannot use name based virtual hosts in Apache if the protocol isn't
HTTP/1.1, it seems. Even if there's a host header it's being ignored in
HTTP/1.0 - which is technically the best solution, because it's a
violation of the HTTP/1.0 protocol.
So... is there any way at all to make nginx talk HTTP/1.1 to the backend
server, or do I really have to set up IP based virtual hosts and
seriously bloat up both nginx's and Apache's config? I don't understand
why it would use a different protocol than the original request at all
in first place - why not pass the request as it was made?
