title: history.go (-1) not working in internet explorer
body: <p>When I use the history.go(-1) command as follows it works fine, but takes very long to reaload the page.</p>
  
  <pre><code>&lt;script type="text/javascript" language="javascript"&gt;
       javascript:history.go(-1);
  &lt;/script&gt;
  </code></pre>
  
  <p>But when I try and use it in my php code, it just gives me an error "Internet Explorer cannot display the webpage". Here is my code</p>
  
  <pre><code>&lt;?php header(sprintf("Location: %s", "javascript:window.history.go(-1);")); ?&gt;
  </code></pre>
  
  <p>In ff and chrome this works really well, it quickly returns to previous page, without reloading. Not so in ie.</p>
