ReverseProxy: Send hostname upstream

[fatzopilot]

One addition:

Actually, I am not trying to proxy one server (as I learned, this can be
done by just assigning "proxy_set_header Host " someServer.akamai.com",
but if possible several (I just reverted to one here for boiling down
the issue).

So I am using an upstream directive like this
upstream  akamaiBackend {
   server someServer1.akamai.com:80;
   server someServer2.akamai.com:80;
   server someServer3.akamai.com:80;
}

Maybe it is possible to define the header_host to be forwarded in the
upstream directive? Haven't found it in the docs, though...

Thanks
