the only to force auto logout is with the session timeout settings, session timeout os set on the server:
12812.htm
your log out page should have the following code in it before the doctype tag to clear the sessions:
<?php
if (!isset($_SESSION)) {
session_start();
}
?><?php
if ("" == ""){
// WA_ClearSession
$clearAll = TRUE;
$clearThese = explode(",","");
if($clearAll){
foreach ($_SESSION as $key => $value){
unset($_SESSION[$key]);
}
}
else{
foreach($clearThese as $value){
unset($_SESSION[$value]);
}
}
}
?>
