Frontend
The persistent login script (persistent-login.js) checks if persistent_login_used cookie is present. If there is such a cookie the script then checks if the customer is already logged-in. If not it sends a post request to persistent_login/persistent/login Backend code performs login when a customer enters a fully cached page and Javascript detects that it is not logged in currently. If the customer logged in during the current request the page is reloaded.
