如何删除Java servlet中的cookie？

我试过这个:http: //www.jguru.com/faq/view.jsp？EID = 42225

编辑:以下现在成功运作它似乎是以下的组合:

response.setContentType("text/html");

和

cookie.setMaxAge(0);

在我做之前:

//remove single signon cookie if it hasn't been validated yet
response.setContentType("text/html");
Cookie cookie = new Cookie(SSORealm.SSO_COOKIE_NAME, "");
cookie.setDomain(SSORealm.SSO_DOMAIN);
cookie.setMaxAge(-1);
cookie.setPath("/");
cookie.setComment("EXPIRING COOKIE at " + System.currentTimeMillis());
response.addCookie(cookie);

根据文档关闭浏览器时,cookie会过期.

负值表示cookie不会持久存储,并在Web浏览器退出时被删除.零值会导致cookie被删除.

要使Cookie过期的完整工作代码段是:

//remove single signon cookie if it hasn't been validated yet
response.setContentType("text/html");
Cookie cookie = new Cookie(SSORealm.SSO_COOKIE_NAME, "");
cookie.setDomain(SSORealm.SSO_DOMAIN);
cookie.setMaxAge(0);
cookie.setPath("/");
cookie.setComment("EXPIRING COOKIE at " + System.currentTimeMillis());
response.addCookie(cookie);
