need help... :'(

I've tried using the sessions class, add the session data in the database and I added a header in the view but the results still, I can access the previous page by pressing the back button.

my controller

Code:
$data = array(

        'Username' => $this->input->post('Username'),

        'is_logged_in' => true );

$this->session->set_userdata($data);

my view header

Code:
&lt;meta http-equiv="content-type" content="text/html; charset=iso-8859-1" /&gt;

&lt;meta http-equiv="Cache-Control" content="no-cache, no-store, must-revalidate, no-transform, max-age=0, post-check=0, pre-check=0" /&gt;

&lt;meta http-equiv="pragma" content="no-cache" /&gt;

my logout function

Code:
function logout()

{    

   $data = array($this->session->unset_userdata('Username'),  

                 $this->session->unset_userdata('is_logged_in'));

   $this->session->sess_destroy($data);

   redirect('login','refresh');

}

I use mozilla as a browser

Thank you... Smile
