In server mode a session successfully 50retrieved from internal or external cache is counted as a hit. 51 52SSL_CTX_sess_cb_hits() returns the number of successfully retrieved sessions 53from the external session cache in server mode. 54 55SSL_CTX_sess_misses() returns the number of sessions proposed by clients 56that were not found in the internal session cache in server mode. 57 58SSL_CTX_sess_timeouts() returns the number of sessions proposed by clients 59and either found in the internal or external session cache in server mode, 60 but that were invalid due to timeout. These sessions are not included in 61the SSL_CTX_sess_hits() count. 62 63SSL_CTX_sess_cache_full() returns the number of sessions that were removed 64because the maximum session cache size was exceeded. 65 66=head1 RETURN VALUES 67 68The functions return the values indicated in the DESCRIPTION section. 69 70=head1 SEE ALSO 71 72L<ssl(3)|ssl(3)>, L<SSL_set_session(3)|SSL_set_session(3)>, 73L<SSL_CTX_set_session_cache_mode(3)|SSL_CTX_set_session_cache_mode(3)> 74L<SSL_CTX_sess_set_cache_size(3)|SSL_CTX_sess_set_cache_size(3)> 75 76=cut 77
