For load balanced applications, you can now add a Health Check path to enable active health checks. 🎉
When enabled, Caddy will make an HTTP request every 30 seconds to determine if your application is healthy or not. If your application does not respond with a
200 OK, Caddy will remove the server from the load balancer until the next check that succeeds.
Plus, Rails 7.1 will ship with an
/up route specifically for health checks like these out of the box!
