end to end encryption if using cascade connection

[shakibamoshiri]

If a client connects to server-A and server-A has CC (cascade connection) to server-B (as an exit node)
Is traffic between the client and server-B end-to-end encrypted ?
I think it is not since the client connected to a HUB of server-A and that HUB is connected using another username to a HUB of server-B

Code: Select all

model 1
client <=====> ( server-A HUB <==> CC ) <=====> server-B

please correct me if I am wrong

And what about when the server-A does not authenticate a user and just acts as relay server using CC and forwards the client request to server-B
Is this one end-to-end encrypted ? I think it is but am not sure.

Code: Select all

model 2
client <=====> ( CC ) <=====> server-B

please correct me if I am wrong

NOTE about model 2
This model is a split tunnel not a full-tunnel using local bridge for all nodes (the client, server-A and server-B)
