下面的配置运行得很好，但我的客户端得到的是 squid ip 地址，而不是他们自己的公共地址，所以我follow_x_forwarded_for在 backend.conf 中添加了允许 localhost这个帖子.然后我开始收到错误。
Frontend log -> kid1| temporary disabling (Forbidden) digest from localhost
backend log -> 0 :: TCP_DENIED/403 4180 GET http://backend-kid2:4002/squid-internal-periodic/store_digest - HIER_NONE/- text/html

但客户端仍然可以获取 squid 服务器的 ipaddress，因此我尝试
http_port localhost:300${process_number}
http_port localhost:400${process_number} tproxy在 backend.conf 中添加并发现以下错误：
