wordpress varnish vcl配置文件

如需使用varnish作wordpress缓存，已经开发有一键包https://www.centos.bz/lampv/
使用如下配置文件，建议安装wordpress插件Varnish HTTP Purge来自动清除缓存，此配置文件实现的功能如下：
1、varnish作为前端，使用80端口
2、允许127.0.0.1和www.centos.bz清除缓存
3、在缓存之前，删除常见静态文件的cookie。
4、http.x-forwarded-for获取真实IP。
5、不缓存wordpress后台页面，不缓存已登录的用户和保留评论者cookie。
6、后端服务器状态检查，如发生故障，继续以旧缓存内容服务。
下面是配置文件内容：
