Redirecting To Login Page If Session Expired during or before Ajax request is made

Not sure if anyone is still having an issue with this...but i was so i'll post my work-around.

What I did was place a bit of code at the beginning of each method that is called via AJAX to determine whether the user was still logged in:

Code:

$is_logged_in = $this->session->userdata('is_logged_in');
if(!$is_logged_in){
    echo 'INVALID';
    return false;
}

The above simply sends a message back and stops running if the user is not logged in anymore.

Then in my Js file, I first check the response to determine if it equals 'INVALID' and if so I do a simple Js refresh:

Code:

if(response=='INVALID'){
    location.reload(true);
    return false;
}

The refresh then sends them seamlessly back to the login page. This works perfectly for me. I'm sure it can be re-written to be more efficient, and if someone has that idea then I'd love to update it, but for now, this works well
