Page Refresh poblem

[eluser]Swayam[/eluser]

Code:

$data = array('uname'=>$this->input->post('e_uname'),...

ok..this is also a good way..direct assigning..removing unnecessary variables..i will follow it next time..yes..definitely i m taking inputs from the user..i also have to put validation in it..
Sir,i need your help once again..i have a logout link..which is working fine..here is the code..

Code:

public function logout()
{
  $this->session->sess_destroy();
  redirect('http://localhost/CodeIgniter_2.1.2/index.php/login/flogout','refresh');
}
function flogout()
{

$this->load->view('login_page','refresh');
}

but there is one problem ..when user comes to login page after logout and again pressing back button..then it shows the previous page..which should not be happen..Glad if u help your student..!!
