Virtual hosts

Let's say you want to host domains first.com and second.com.

Create folders for their files:

	<?php

	function get_web_page( $url ){
	$options = array(
	CURLOPT_RETURNTRANSFER => true, // return web page
	CURLOPT_HEADER => false, // don't return headers
	CURLOPT_FOLLOWLOCATION => true, // follow redirects
	CURLOPT_ENCODING => "", // handle all encodings
	CURLOPT_USERAGENT => "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.17 (KHTML, like Gecko) Chrome/24.0.1312.52 Safari/537.17", // who am i
	CURLOPT_AUTOREFERER => true, // set referer on redirect

	#!/usr/bin/env bash
