Cookie Update

[Jianhong]

Hi, gurus,   I searched this archive, but didn't find the answer.   I want to update the cookie which is added when the user first logged on using the following code, but it has no use, can anyone tell me why.      Cookie cs[] = request.getCookies();   if (cs != null) {     for (int i=0; i<cs.length; i++) {      if (cs[i].getName().equals("CookieID")) {       bFind = true;       cs[i].setValue(String.valueOf(new Date().getTime()));       cs[i].setComment(String.valueOf(new Date().getTime()));       cs[i].setMaxAge(60*60*24);       break;      }     }    }   Thanks in advance.   Jianhong
