多个 sequence 之间共享 Cache 的问题

[CalmLong]

如题，使用了两个 Server，当 main_sequence 和 second_sequence 都使用 _default_cache 时，它们会共享缓存

我这样用是因为 V2Ray 可以通过 IP 分流，所以我不要求 mosdns 返回无污染的 IP，只要返回结果就好了；然后发现如果先用 second_sequence 得到污染的结果然后缓存，此时用 main_sequence 匹配时返回的也是 second_sequence 缓存的污染结果；现在的解决方法是 second_sequence 不开启缓存

插件是独立的 .default cache 是一个插件，当然是一个缓存。

配置俩缓存插件。
