Cookie []cookies  = request.getCookies();
for(int i = 0; cookies!=null && i < cookies.length; i++){
    Cookie ck = cookies[i];
    out.print(ck.getName() + "=" + ck.getValue() + "<br/>");

    if(ck.getName().equals("visit"))
        visit = Integer.parseInt(ck.getValue());
}

//写入Cookie
visit = visit + 1;
