Can MAG on Active/Passive do stateful failover?
Are users able to maintain their session during failover?
If the cluster fails over to the passive node, all sessions should be transferred to the passive node.
The kb article does make sense as all other connection besides core access (through the rewriter) is specific to each node. This means if the cluster fails over, the user will be disconnected and will need to reconnect. Is your concern will only RDP sessions? If so, are we talking about using Juniper Terminal Service like WTS? I can run a few tests to reconfirm my understanding.
