Smarty

[mpk]

I have a login.php like this:

ini_set('session.name', 'mysession');
ini_set('session.cookie_lifetime', 1800);
session_start();
.....
$smarty->display("login.tpl");

And a logout like this:

session_start();
session_unset();
setcookie (session_name(), '', (time () - 2592000), '/', '', 0);
session_destroy();
header("Location: login.php");
exit;

It looks like that the session (and cookies and everything) is effectively destroyed but when i come again to the login screen and I press reload from my browser it informs me that my form has to be resend and if I confirm I login again. I think I'm missing something simple here (clear cache or something like this?) but I cannot find what.

Any ideas please?
Thanks.-

Challenge-Response was what I was missing. Not exactly smarty...
Many thanks for this.
