keepalive and "down" flag

Frank Liu

If I use keepalive between nginx and upstream backend servers, and later add the "down" flag to one of the servers, will nginx stop sending traffic to it immediately or will it still send requests using the existing keepalive connection, just not creating any new connection? Is the "down" flag only consulted for creating new upstream connections or is it also for every request on existing/keepalive connection?
