show login form using ajax after session expiration in grails <p>I had a list of users displayed in a table whose <strong>session</strong> expires after 20min, but after expiration it doesn't go to login page without refreshing and I want to show a pop-up to display a login form which after login will keep me to the same url. I'm working on <em>grails</em>; can anyone help with it?</p>
