=head1 DESCRIPTION
SSL_CTX_sess_set_get_cb() sets the callback function which is called,
whenever a SSL/TLS client proposed to resume a session but the session
could not be found in the internal session cache (see
-L<SSL_CTX_set_session_cache_mode(3)|SSL_CTX_set_session_cache_mode(3)>).
+L<SSL_CTX_set_session_cache_mode(3)>).
(SSL/TLS server only.)
SSL_CTX_sess_get_new_cb(), SSL_CTX_sess_get_remove_cb(), and
In order to allow external session caching, synchronization with the internal
session cache is realized via callback functions. Inside these callback
functions, session can be saved to disk or put into a database using the
-L<d2i_SSL_SESSION(3)|d2i_SSL_SESSION(3)> interface.
+L<d2i_SSL_SESSION(3)> interface.
The new_session_cb() is called, whenever a new session has been negotiated
and session caching is enabled (see
-L<SSL_CTX_set_session_cache_mode(3)|SSL_CTX_set_session_cache_mode(3)>).
+L<SSL_CTX_set_session_cache_mode(3)>).
The new_session_cb() is passed the B<ssl> connection and the ssl session
B<sess>. If the callback returns B<0>, the session will be immediately
removed again.
from the internal cache. This happens when the session is removed because
it is expired or when a connection was not shutdown cleanly. It also happens
for all sessions in the internal session cache when
-L<SSL_CTX_free(3)|SSL_CTX_free(3)> is called. The remove_session_cb() is passed
+L<SSL_CTX_free(3)> is called. The remove_session_cb() is passed
the B<ctx> and the ssl session B<sess>. It does not provide any feedback.
The get_session_cb() is only called on SSL/TLS servers with the session id
SSL engine to increment the reference count of the SSL_SESSION object,
Normally the reference count is not incremented and therefore the
session must not be explicitly freed with
-L<SSL_SESSION_free(3)|SSL_SESSION_free(3)>.
