用于登录 WordPress 用户的 Nginx 缓存页面（并向访问者显示管理栏！）

我已经在 WordPress 中设置了带有缓存的 nginx。

我正在使用https://wordpress.org/plugins/nginx-helper/，但是登录页面似乎在不应该被缓存时被缓存（因此显示了登录栏）。

一些未登录的访问者（也没有任何 cookie/浏览器缓存）正在查看登录栏（如果他们点击栏中的任何内容，则会将他们重定向到登录页面）。

此外，当我单击 WordPress 中的清除缓存按钮时，页面仍然提供并显示为XCache HIT......真正清除的唯一方法是通过rm -rf /dev/shm/nginx.

我确实安装了以下模块：

知道我的配置有什么问题吗？
