Our datacenter is load balancing the traffic to our weblogic servers based on an application deployed on each server called probe.ear

It is a simple java app which is accessed by the loadbalancer and if it accessible it will redirect traffic to this server as well.

When we want to remove one node from the loadbalancer we just stop the probe app and new traffic is not redirected to it BUT I am asking myself what about the current requests?

The responses for the current requests are executed (completed). I did not had time to test (will do that first thing when go back to work) but on theoretical level for me it make sense to do so unless the loadbalancer has some special settings.

Does my reasoning make sense to you?

Just to make it clear since it was reported the question is not clear.

Is there a way to configure a load balancer in a way that from a specific moment will not redirect traffic to a certain server without reseting the current requests ?
