You can do it like this
$.ajax({type : 'POST',url : '<?php echo site_url('controllername/methodname')?>'success : function(data){ if(data){ //session available }else{ // expired } });And controller method
function methodname(){ $user_id = $this->session->userdata('user_id'); if($user_id){ echo 1; }else{ echo 0; } }You can wrap ajax request in function and return the result everytime with TRUE or FALSE. Moreover setInterval can call this function for checking session.
