NLB with Socket Communication

Hi,

i have an server application which responses incoming request on socket.

(then incoming request received from a client, server application opens a
socket and sends response to client.
After response ended, the socket is closed by serv. appl.)


my queation is :
in a network configures as NLB Cluster, which node will response. Namely,
will the same node response until the communication ended or else.

Is there a problem NLB Cluster to use such an application that opens socket.

Thanks
