title: permission denied while posting the form which contains textarea with html content
body: <p>Ok, so here's my problem (which I've googled and no help):</p>
  
  <p>I have a form which has the textarea element, and in it I want to write something like:</p>
  
  <pre><code>&lt;table&gt;&lt;tr&gt;&lt;td&gt;123&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;
  </code></pre>
  
  <p>and click submit and i want it to be saved in database. </p>
  
  <p>Now, my code is working if I enter nonHTML characters, but if I enter as above I get:</p>
  
  <pre><code>Forbidden
  
  You don't have permission to access /xxx/sample_posteddata.php on this server.
  
  Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
  </code></pre>
  
  <p>My guess is that somehow my hosting has some security enbaled to disallow this?</p>
  
  <p>I've tried to insert the exact text from the php admin interface and that works fine :?</p>
