  • Patent number: 10069800
    Abstract: An intermediary network device participates in a secure communication session between a server and a client through a proxy client and a proxy server. The proxy client receives a first session ticket from the server that enables the proxy client to resume communications with the server in the secure communication session. The intermediary network device determines a session state of the proxy client and the proxy server. The intermediary network device encapsulates the session state of the proxy client, the session state of the proxy server, and the first session ticket as part of a second session ticket. The second session ticket enables the client to resume communications with the proxy server in the secure communication session. The intermediary network device sends the second session ticket to the client and deletes the first session ticket.

  • Patent number: 9608963
    Abstract: An intermediary network device receives a request for a secure communication session between an endpoint server and an endpoint client through the network device. The secure session between the endpoint server and the endpoint client is divided into a first session and a second session. The first session is between the endpoint server and the network device. The second session is between the network device and the endpoint client. The network device receives a first session ticket from the endpoint server. A session state of a proxy client in the first session, including the first session ticket, is determined. The network device also determines a session state of a proxy server in the second session. The combination of the session state of the proxy client, including the first session ticket, and the session state of the proxy server are encapsulated as part of a second session ticket.
