** [bugs:#1491] Host-Header should be sent first**
**Status:** closed-fixed

rfc7230 recommends that the Host:-header should be sent first:
https://tools.ietf.org/html/rfc7230#section-5.4
  Since the Host field-value is critical information for handling a
  request, a user agent SHOULD generate Host as the first header field
  following the request-line.
If one explicitly sets a Host-header, curl emits such a "custom" Host:-header in the order it was set, i.e. not as  the first header as recommended by rfc7230:
The order is essentially the same with the curl command line tool and the
PHP curl bindings. 
$ nc -l 1234 &
[1] 50827
$ curl -vH 'X-foo: asdf' -H 'Host: asdf' http://127.0.0.1:1234/qwert
*   Trying 127.0.0.1...
