nginx configuration for host-only to fqdn redirecting.

nginx_host_only_to_fqdn_redirect

;Where you have local httpd and client machines receiving domain-name via DHCP, following addition to nginx config
;would often be useful.
;For clarification, client machines get domain-name specified as 'intra.example.com' via DHCP in this example.
;BTW this type of setup is often found in situations where hostname-only name resolution would make things easier, say where
;you have Windows Active Directory in place, or local resources available, like network printers, NAS and so on.
;Whils specifying local domain over DHCP serves well for simple name-resolution applications that does not require FQDN,
;virtual-hosts as typically found configured on web servers would not favor that.
;Specifically, requests to something like 'http://www' must be redirected to 'http://www.intra.example.com', the proper FQDN.
;
;As per nginx documentation, you may have multiple server_name directives each specifying different host-only part of fqdn.

server {
  listen 80;
  server_name www;
  return 301 http://$host.intra.example.com$request_uri;
