title: Adding http:// on form action doesn't return form input values
body: <p>Case 1:</p>
  
  <pre><code>&lt;form action='update.php' method='post'&gt;
  </code></pre>
  
  <p>Case 2:</p>
  
  <pre><code>&lt;form action='http://site.net/update.php' method='post'&gt;
  </code></pre>
  
  <p>Case 1 works fine, but when I add the full site URL including the http:// Case 2 returns an error. It doesn't give the values returned by the form.</p>
  
  <p>Does using http:// or full URL prohibited?</p>
