A cookie is a object with key value pair to store information related to the customer  Main objective is to personalize the customer s experience   An utility method can be created like   private Cookie createCookie String cookieName  String cookieValue        Cookie cookie   new Cookie cookieName  cookieValue       cookie setPath           cookie setMaxAge MAX AGE SECONDS       cookie setHttpOnly true       cookie setSecure true       return cookie      If storing important information then we should alsways put setHttpOnly so that the cookie cannot be accessed modified via javascript  setSecure is applicable if you are want cookies to be accessed only over https protocol   using above utility method you can add cookies to response as   Cookie cookie   createCookie  name   value    response addCookie cookie
