15 | Query, whether a reused session was negotiated during the handshake. | |
16 | ||
17 | =head1 NOTES | |
18 | ||
19 | During the negotiation, a client can propose to reuse a session. The server | |
20 | then looks up the session in its cache. If both client and server agree | |
21 | on the session, it will be reused and a flag is being set that can be | |
22 | queried by the application. | |
