This is the case：
My Caddy represents 10 servers，Now I think，When I have a server downtime，Can you have an interface?Let caddy automatically execute the script that I wrote on the startup server or caddy to start that server。
sorry，My English is not good.A lot of them come from translation。
========================
情况是这样的：
我的caddy代理了10台服务器，现在我想，当我有一台服务器宕机的时候，能不能有什么接口，让caddy自动去执行我自己写的启动服务器的脚本或者caddy去启动那台服务器。
感谢。
