title: validate url without www. or http://
body: <p>I'm looking to validate an URL. I have already a script that validates to not allow <code>www.</code> and <code>http://</code> but i need to also validate for <code>.co.uk</code> <code>.com</code> etc.</p>
  
  <p>My script won't run if they enter something like <code>example.co.ukff</code>.</p>
  
  <p>I have this for a full URL:</p>
  
  <pre><code>^[a-zA-Z]+[:\/\/]+[A-Za-z0-9\-_]+\\.+[A-Za-z0-9\.\/%&amp;=\?\-_]+$/i
  </code></pre>
  
  <p>I just need to validate the end <code>.co.uk</code> or <code>.com</code> etc.</p>
