Abstract:
The present disclosure is directed towards systems and methods of maintaining a session via an intermediary device. A first device intermediary to a client and a plurality of servers receives a packet of a session. The packet of the session includes application protocol data and application session metadata used to maintain a state of an application accessed via the session. The first device marks a session state of the session to an update state. The first device determines that a second device intermediary to the client and the plurality of servers is in a ready state and the session state of the session is in the update state. The first device forwards the application protocol data and the application session metadata of the packet to the second device to maintain, on the second device, the same state of the application accessed via the session provided by the first device.
