Destroy Cookie while Logging out.

I was facing a problem where while a person logs out his session is invalidated but the JSESSIONID still remained in the browser. As a result while logging in the Java API used to get the request from the browser along with a JSESSIONID(Just the ID since the session was invalidated) and would create the new session with the same ID. To fix this problem I used the above code so that whenever a user logs out the entire JSESSIONID becomes empty and thus cookie wont exist for that site.Anyone using JAVA can utilize this in their code.

@RequestMapping(value = "/logout", method = RequestMethod.POST)
public void logout(HttpServletRequest request,
HttpServletResponse response) {
/* Getting session and then invalidating it */
HttpSession session = request.getSession(false);
if (request.isRequestedSessionIdValid() && session != null) {

 * This method would edit the cookie information and make JSESSIONID empty
 * while responding to logout. This would further help in order to. This would help
 * to avoid same cookie ID each time a person logs in
 * @param response
private void handleLogOutResponse(HttpServletResponse response) {
Cookie[] cookies = request.getCookies();
for (Cookie cookie : cookies) {
