如何操作，我正在使用 Squid v3.3.8，我需要创建 HTTP 旋转代理服务器来通过一组预定义代理发送所有请求（我正在自动更新 squid 配置以更新一组工作代理）。
我的输出代理不够快也不可靠，所以如果其中一些代理响应不够快，我不希望 squid 等待，我最好希望其他代理更好，并且永远不要回到有问题的代理。
我的配置如下
# Basic configuration
visible_hostname squid_1
unique_hostname squid_1
http_port 3130
pid_filename /home/vagrant/projects/squid_1.pid
dns_v4_first on
peer_connect_timeout 3 seconds
dead_peer_timeout 3 seconds
server_persistent_connections off
http_access allow all
# Proxies list

cache_peer PROXY_HOST parent PROXY_PORT 0 connect-fail-limit=1 round-robin no-query name=node3796185266 login=login3796185266:PASSWORD
never_direct allow all
这是我所看到的缓存日志

问题是我不希望我死去的父母复活（是的，听起来很奇怪）。
而且我也不太清楚 squid 如何检测我的对等端是否宕机。我禁用了ICP查询通过设置选项为每个对等点no-query提供端口 0，但dead_peer_timeout它仍然认为我的对等点在超时后已经死亡，尽管它正在使用电感耦合等离子体 根据文档。
更新：添加squid -v输出：
