title: window.location - how to open a blank window
body: <p>I have a login script and currently when all is done the client is redirected to the billing page.</p>
  
  <p>I'd like this page to open in a new browser window not the existing one as the current code does.</p>
  
  <pre><code>function go_to_private_pageb() {
      window.location = '../########/billing.php'; // Members Area
  }
  </code></pre>
