在我的服务器，我有清漆设置。 我使用wordpress并安装了w3总caching插件。 我已经设置该插件来清除我的清漆（清漆3）caching。 但它不工作！ 在我的系统日志中，有一些像下面显示的错误…请帮助我！

假设清漆3
if (req.request == "PURGE") { if (!client.ip ~ purge) { error 405 "Not allowed."; } return(lookup); }
这个块是不正确的，当客户端不允许清除尝试的时候会触发405错误，但是如果有效的客户端尝试这样做，那么实际上没有任何东西可以清除，而是从caching中返回内容。
if (req.request == "PURGE") { if (!client.ip ~ purge) { error 405 "Not allowed."; } ban("req.url ~ "+req.url); error 200 "Purged"; }
这个块应该做你需要做的事情。
