The nginx variable $server_name is the first name in the server_name
directive list.

The nginx variable $http_host is the Host: header sent by the client.

The nginx variable $host is $http_host if it is defined, and $server_name
if not.

The typical nginx fastcgi configuration will set SERVER_NAME to
$server_name (within fastcgi.conf) and HTTP_HOST to http_host (because
that's what happens to client headers). So you can check those in
your script.

If you wish, you can add your own "fastcgi_param HOST $host" setting
and check that, or you could set SERVER_NAME to be $host and continue
checking that one.
