title: How to get the full URL of a Drupal page?
body: <p>I need to be grabbing the URL of the current page in a Drupal site. It doesn't matter what content type it is - can be any type of node.</p>
  
  <p>I am NOT looking for the path to theme, or the base url, or Drupal's get_destination. I'm looking for a function or variable that will give me the following in full:</p>
  
  <p><a href="http://example.com/node/number" rel="noreferrer">http://example.com/node/number</a></p>
  
  <p>Either with or without (more likely) the <code>http://</code>.</p>
