競合他社が当社のコンテンツを盗んでおり、いくつかの調査により、当社のログで競合他社の IP アドレスを見つけました。Varnish を使用して 2 番目の古いキャッシュからサイトを提供する方法を知っている人はいますか? 彼らにサイトを手に入れてもらいたいのですが、古いコンテンツだけです。

これが機能するかどうかもわかりませんが、Varnish 3 の敬虔なページを使用して思いついたのは次のとおりです。私はここでそれをやりますか？

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;
 }
}

これが私の現在のdefault.vclです

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

sub vcl_recv {
  # Add a unique header containing the client address
  remove req.http.X-Forwarded-For;
  set    req.http.X-Forwarded-For = client.ip;
}


sub vcl_recv {

ターゲットと同じハッシュを取得するため、そのようなすべての人のためにキャッシュ内の ttl を上書きします。

同様に行う必要があるのは、次のようなものも追加することです。

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";
    }
}
