Help..Session always needs manual refresh to show correct session. - El Forum - 08-12-2012

Hi all...
Currently i'm using CI 2.1.2 and store session using database. After successful login, login controller redirect to home controller and displaying another user session. If users press CTRL+F5 (manual refresh), it showing correct user session.

Autoload Libraries: Session,Database
Autoload Helper: Url

Config

Code:
$config['sess_cookie_name'] = 'cisession';

$config['sess_expiration'] = 3600;

$config['sess_expire_on_close'] = TRUE;

$config['sess_encrypt_cookie'] = TRUE;

$config['sess_use_database'] = TRUE;

$config['sess_table_name'] = 'ci_sessions';

$config['sess_match_ip'] = FALSE;

$config['sess_match_useragent'] = TRUE;

$config['sess_time_to_update'] = 3600;

Controller: Login

Code:
class Login extends CI_Controller

{

 function __construct() {

  parent::__construct();

  $this->load->helper('form');

  $this->load->model('login_model');

 }

 function index() {

  $this->load->view('login');

 }

 function check() {

  $username = $this->input->post('username');

  $password = $this->input->post('password');

  if($this->login_model->check($username,$password)) {

   $this->session->set_userdata(array(

    array(

     'username' => $username

     ,'logged_in' => TRUE

    )

   ));

   redirect('/home','refresh');

  } else {

   $this->load->view('login');

  }

 }

}

Controller: Home

Code:
class Home extends CI_Controller

{

 function __construct() {

  parent::__construct();

 }

 function index() {

  $this->load->view('home',array(

   'user' => $this->session->userdata('username')

   ,'sessid' => $this->session->userdata('session_id')

  ));

 }

}

View: Home

Code:
&lt;html&gt;

&lt;head&gt;&lt;title>Welcome Home&lt;/title&gt;&lt;/head>

&lt;body&gt;

&lt;?php echo "Welcome back, $user"; ?&gt;

&lt;/body&gt;

&lt;/html&gt;

Any suggestion?
Thanks before,
F.Rochim

For one take the forward / off of your redirect to home.

@InsiteFX: I've took off the forward / and some of users still getting wrong session. My database is MySQL and engine for ci_session is InnoDB.
Do i have to switch back to MyISAM for ci_session?

The database engine should not matter.

Try turning of the webpage caching for that page.

@InsiteFX: I'm sorry, what do you mean with turning of webpage caching?
Do i have to set

Code:
$this->output->cache(5)

above

Code:
$this->load->view('home')

Code:
// change to what you need.

$last_update = 3600;

$this->output->set_header('Last-Modified: '.gmdate('D, d M Y H:i:s', $last_update).' GMT');

$this->output->set_header("Cache-Control: no-store, no-cache, must-revalidate");

$this->output->set_header("Cache-Control: post-check=0, pre-check=0");

$this->output->set_header("Pragma: no-cache");

This is just to see if you are having a webpage caching problem with your sessions.

@InsiteFX: So far no users with wrong session after successful login. Thanks.
What i've learned from this problem is everytime i want to show data from session i have to set of webpage caching to off.
This session problem is solved.
