Description:
When stopping envoy by using curl -X POST http://localhost:15000/drain_listeners?graceful
Envoy only sending Connection: CLOSE on HTTP1, that means idle connection will be Established after idle_timeout at most.
Background:
We are building AI Gateway based on Envoy, we hope idle_timeout could be large enough.
Meanwhile we hope downstream idle connections could be closed as soon as possible, so that the the Gateway could be shutdown as early as possible.
[optional Relevant Links:] https://www.envoyproxy.io/docs/envoy/latest/operations/admin#operations-admin-interface-drain
Maybe close downstream idle connection could be the default behaviour or add a new configuration to enable it.
