删除ie cookie
?
Cookie[] cookies = request.getCookies();if (cookies != null) {for (int i = 0; i < cookies.length; i++) {Cookie cookie = cookies[i];if (USERCOOKIENAME.equals(cookie.getName())) {//这里是关键，在ie中必须将value设置为空，ie中的cookie才会真正清楚掉，而ff则不是必要的cookie.setValue("");cookie.setDomain("ddmap.com");cookie.setPath("/");cookie.setMaxAge(0);response.addCookie(cookie);request.getSession().invalidate();}}}??
