idleTimeout property
A keep-alive connection with no new request for this long is closed. A request head must also come whole in this time. Behind a load balancer, set it longer than the idle timeout of the balancer (eg. 65 seconds for AWS ALB, which keeps connections for 60 seconds). Else Dox may close a connection the balancer still uses, and clients get 502. Default 30 seconds.
Implementation
final Duration idleTimeout;
