title: URI has disallowed characters in... IE
body: <p>I have this new problem with IE, it keeps getting this URI disallowed characters error in Internet explorer.</p>
  
  <p>The calls are made through AJAX and it works fine in the <strong>LOCALHOST</strong>, but on the server, it doesn't work at all.</p>
  
  <p>Examples of the url called (sorry, had to xxxx some parts for disclosure issues)</p>
  
  <pre><code>http://sandbox.xxxxxxxxx.pt/beta1/gestao/xxxxxxx_ctr/?%23&amp;_=1302607702688 (this one doesn't work in IE)
  
  http://localhost/xxxxxxxxx/gestao/xxxxxxx_ctr/?%23&amp;_=1302608090193 (this one does)
  </code></pre>
  
  <p>These permitted uri chars work like a charm for the "good" browsers.</p>
  
  <pre><code>$config['permitted_uri_chars'] = 'a-z 0-9~%.:_\+\-';
  </code></pre>
  
  <p>Does anyone happens to know the solution to this problem and would be kind enough to help me?</p>
  
  <p>Thank you.</p>
