title: php reload page without posting data
body: <p>I'm trying to refresh a page without sending POST from the previous time.</p>
  
  <p>I've tried</p>
  
  <pre><code>window.open("postme.php?r=t", "_self");
  </code></pre>
  
  <p>Which appends a <code>?r=t</code> to the end but it doesn't appear to refresh the page as the page displays a number of files in a directory which hasn't change even though I have moved or deleted them.</p>
  
  <p>Can you specify the URL in <code>window.location.reload();</code>?</p>
  
  <p>Any ideas?</p>
  
  <p>Thanks</p>
