SSL_session_reused - query whether a reused session was negotiated during handshake
SYNOPSIS
#include <openssl/ssl.h>

DESCRIPTION

NOTES
During the negotiation, a client can propose to reuse a session. The server
then looks up the session in its cache. If both client and server agree
on the session, it will be reused and a flag is being set that can be
queried by the application.
RETURN VALUES
The following return values can occur:
- 0
-
A new session was negotiated.
- 1
-
A session was reused.
