title: HTML sends x y POST data with no inputs - how is this possible?
body: <p>I am trying to logging using php's curl.</p>
  
  <p>I am using LiveHTTPHeaders to see what headers are sent.</p>
  
  <p>When I login through form it sends </p>
  
  <pre><code>action=autorize&amp;login=myname&amp;pass=mypass&amp;x=14&amp;y=10
  </code></pre>
  
  <p>I can see <code>action</code>, <code>login</code>, <code>pass</code> <code>&lt;inputs&gt;</code>.<br>
  The problem is - there are no <code>x</code> and <code>y</code> inputs. And they are random all the time. I searched all html, but there are definitely no any x, y or their numbers.</p>
  
  <p>How is that possible at all? </p>
