title: GET parameters in the URL with CodeIgniter
body: <p>I know that codeIgniter turns off GET parameters by default. </p>
  
  <p>But by having everything done in POST, don't you get annoyed by the re-send data requests if  ever you press back after a form submission?</p>
  
  <p>It annoys me, but I'm not sure if I want to allow GET purely for this reason.</p>
  
  <p>Is it such a big security issue to allow GET parameters too?</p>
