Learn how to remove cookies from a request while logging out from a website/application.

Session cookies store information related to the user and other data related to the user when a user logs into a website or in these days, on visiting a website.

Let’s say you have a cookie called Session in your request, to invalidate it you need to empty its value, path and its max age.

cookie.setValue("");
cookie.setPath("/");
cookie.setMaxAge(0);
response.addCookie(cookie);

And add it to the response, of course. Otherwise the cookie would still remain active in the request.

The full code would look like..

Cookie[] cookies = request.getCookies();
        if (cookies != null)
            for (Cookie cookie : cookies) {
                if ("Session".equals(cookie.getName())) {
                    System.out.println("LOGGIN OUT ! Session cookie found.. Removing it !");
                      cookie.setValue("");
                      cookie.setPath("/");
                      cookie.setMaxAge(0);
                      response.addCookie(cookie);
                }
            }
