太平洋育儿网（Tpcache插件Redis缓存评论者信息解决方案）

太平洋育儿网：继上一篇文章，使用TpCache插件之后，会缓存上一个评论用户的邮箱信息，这是非常不好的一件事情，因为会泄露评论者的邮箱。

根据修复typecho使用缓存插件TpCache时缓存评论人的信息的问题 – 至道小博 (zdaoxb.com)这篇文章，并结合最新版本的Handsome主题（8.2.0）对评论的代码做了一些改造，把PHP输出cookie给修改成前端js输出，其中不必要的代码做了注释，如需使用请先备份现有的comments.php文件。

下面是完整的commens.php文件代码，如果使用的是未修改过此代码的朋友可以直接对comments.php中的代码进行替换。建议替换前先备份一份源文件，以备不时只需。

路径为：/usr/themes/handsome/component/comments.php
