TCP VIP: client -> VIP connection behavior when VIP -> server connection is closed

Specifically talking about Citrix netscalers but I’m guessing the behavior is similar in other implementations

The documentation mentions that in TCP VIP mode there is 1:1 mapping between the client -> VIP connection and VIP -> server connection. So in this case what happens to client side connection when:

  1. VIP -> server connections times out (due to timeout set on VIP) which I think means that the VIP sends RST to server
  2. Server aborts connection to VIP with RST
  3. Server closes connection to VIP gracefully

Basically trying to understand how these events affect existing client side connections with the client actively trying to use them. Are they closed because of the 1:1 mapping as well or the VIP somehow handles these events transparently to the client?
