Answer 1

You can check user's session by making the ajax call and wrap it into the setInterval jquery's function like

setInterval(function() {
  // Do something every 1 minute 
$.ajax({
type : 'POST',
url  : ''
success : function(data){
if(data){
   //your session is not expired
}else{
   //your session is already expired
 window.location.href="your url"; // or you can redirect from here also
} 
});
}, 60000);


 //This function checks your session 
 function check_session(){
    $id = $this->session->userdata('id');
   if($id ){
         echo 1;
   }else{
         echo 0;
   redirect('your register controller');//redirect from here or you can redirect in the ajax response
   }

  die();
 }

Hope it makes sense
