如何在Java Servlet中删除cookie?

我尝试了这个:http : //www.jguru.com/faq/view.jsp?EID=42225

编辑:以下内容现在可以成功运行,它似乎是以下各项的组合:

response.setContentType("text/html");

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,并且在Web浏览器退出时将被删除。零值将导致cookie被删除。

使Cookie失效的完整工作片段为:

//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);
