prefer `target.hostname` over `target.host`

Created by: Filirom1

Hi,

I struggled to debug an Error: getaddrinfo ENOENT.

I parsed my target string with url

> require('url').parse('http://127.0.0.1:3000/')
{ protocol: 'http:',
  slashes: true,
  host: '127.0.0.1:3000',
  port: '3000',
  hostname: '127.0.0.1',
  href: 'http://127.0.0.1:3000/',
  pathname: '/',
  path: '/' }

And pass this object to node-http-proxy.

Then the following code is executed :

outgoing.host    = this.target.host;
outgoing.port    = this.target.port;

reverseProxy = this.target.protocol.request(outgoing, function (response) {

But host === '127.0.0.1:3000', and it fails.

That's why I would prefer

outgoing.hostname    = this.target.hostname;

because hostname always === '127.0.0.1'

This is also a nodejs recommendation:

http://nodejs.org/api/http.html#http_http_request_options_callback

host: A domain name or IP address of the server to issue the request to. Defaults to 'localhost'. hostname: To support url.parse() hostname is preferred over host
