安装nginx依赖扩展，当typecho更新时调用http-cache-purge删除缓存，当命中缓存时调用lua清除set-cookie head，防止缓存的设置cookie header发送给所有人。
1 | apt install libnginx-mod-http-cache-purge libnginx-mod-http-lua |
http内添加：

typecho清除缓存插件：
https://github.com/typecho-fans/plugins/tree/master/Ncache
typecho默认在用户评论后会在cookie内设置用户名和邮箱信息，并在服务端读取cookie在html内写入相关信息，这样用户信息被缓存所有人都可以看到，可参考下面方法修改模板用js读取cookie内用户信息。
