如何清除第二个缓存到特定的IP

我有一个竞争对手窃取我们的内容，并且由于一些侦查，我在我们的日志中发现了他们的IP地址。有谁知道我可以如何使用Varnish从第二个陈旧的缓存中为我们的网站提供服务？我希望他们获得该网站，但只是旧内容。如何清除第二个缓存到特定的IP

我甚至不确定这是否可以工作，但这里是我想出了使用Varnish 3尊敬页面的原因。我会在这里做这个诀窍吗？

backend longcache { 
    .host = "127.0.0.1"; 
    .port = "8080"; 
    .connect_timeout = 6s; 
    .first_byte_timeout = 3s; 
    .between_bytes_timeout = 3s; 
} 

acl longcachegroup { 
    "255.255.255.255";  // the bad ip 
} 

if (client.ip ~ longcachegroup) { 
    set req.backend = longcache; 

    sub vcl_fetch { 
if (req.url ~ "^/*") { 
    unset beresp.http.cookie; 
} 

# A TTL of Long ass time minutes 
    set beresp.ttl = 999999999999s; 
} 
}

这是我目前的default.vcl

backend default { 
    .host = "127.0.0.1"; 
    .port = "8080"; 
    .connect_timeout = 600s;

你会被重写你的TTL缓存中的每个人都一样，因为它会得到相同的哈希值作为你的靶向一个。

什么，你需要做的，以及是也添加类似：

sub vcl_hash { 

    ### these 2 entries are the default ones used for vcl. Below we add our own. 
    set req.hash += req.url; 
    set req.hash += req.http.host; 

    if (client.ip ~ longcachegroup) { 
     set req.hash += "longcachegroup"; 
    } 
}
