purge varnish with curl

varnish中配置purge如下：

acl purge {
        "localhost";
        "192.168.55.0"/24;
}

sub vcl_recv {
        # allow PURGE from localhost and 192.168.55...

        if (req.request == "PURGE") {
                if (!client.ip ~ purge) {
                        error 405 "Not allowed.";
                }
                return (lookup);
        }
}

sub vcl_hit {
        if (req.request == "PURGE") {
                purge;
                error 200 "Purged.";
        }
}

sub vcl_miss {
        if (req.request == "PURGE") {
                purge;
                error 200 "Purged.";
        }
}

如果要purge: http://img.notsobad.me/xxx/abc.jpg， 在服务器上执行：

curl -X PURGE http://img.notsobad.me/xxx/abc.jpg

这样写一直报405 not allowed, 想了下，也许是访问img.notsobad.me时，走的时外网网卡，varnish识别处的ip是外网ip，根据上面的配置应该走loopback才对，so：

curl -X PURGE http://127.0.0.1/xxx/abc.jpg

即可。
