With refresh, I don't think you can do that, since document.referrer only refers to the URL where you came from to your current url. You can go back two pages by window.history.go(-2), but that won't refresh the page, and for security reasons, you can't get the URLs from window.history: if you could get previous URLs, you could possibly steal session tokens that were kept in the address bar. – jeoj Sep 17 '15 at 08:06
