如何

可以使用以下脚本小程序删除cookie mycookie：

 <％
 Cookie killMyCookie = new Cookie（mycookie，null）; 
 killMyCookie.setMaxAge（0）; 
 killMyCookie.setPath（/）; 
 response.addCookie（killMyCookie）; 
％>

从请求对象中获取cookie，并使用 setMaxAge（0），然后将cookie添加到响应对象。 p>

How can I delete a cookie from within a JSP page?

A cookie, mycookie, can be deleted using the following scriptlet:

<%
     Cookie killMyCookie = new Cookie("mycookie", null);
     killMyCookie.setMaxAge(0);
     killMyCookie.setPath("/");
     response.addCookie(killMyCookie);
%>

How do I delete a cookie set by a servlet?

Get the cookie from the request object and use setMaxAge(0) and then add the cookie to the response object.
