💖 SSL_CTX_SESS_NUMBER 💖

okay bestie, so this is from the OpenSSL manual, section 3SSL — it's the one about peeking at your session cache stats ✨

🌸 NAME 🌸

SSL_CTX_sess_number, SSL_CTX_sess_connect, SSL_CTX_sess_connect_good, SSL_CTX_sess_connect_renegotiate, SSL_CTX_sess_accept, SSL_CTX_sess_accept_good, SSL_CTX_sess_accept_renegotiate, SSL_CTX_sess_hits, SSL_CTX_sess_cb_hits, SSL_CTX_sess_misses, SSL_CTX_sess_timeouts, SSL_CTX_sess_cache_full — literally all of them just obtain session cache statistics 👑

✨ SYNOPSIS ✨

#include <openssl/ssl.h>

long SSL_CTX_sess_number(SSL_CTX *ctx);
long SSL_CTX_sess_connect(SSL_CTX *ctx);
long SSL_CTX_sess_connect_good(SSL_CTX *ctx);
long SSL_CTX_sess_connect_renegotiate(SSL_CTX *ctx);
long SSL_CTX_sess_accept(SSL_CTX *ctx);
long SSL_CTX_sess_accept_good(SSL_CTX *ctx);
long SSL_CTX_sess_accept_renegotiate(SSL_CTX *ctx);
long SSL_CTX_sess_hits(SSL_CTX *ctx);
long SSL_CTX_sess_cb_hits(SSL_CTX *ctx);
long SSL_CTX_sess_misses(SSL_CTX *ctx);
long SSL_CTX_sess_timeouts(SSL_CTX *ctx);
long SSL_CTX_sess_cache_full(SSL_CTX *ctx);

twelve little functions, all taking a <italic>ctx</italic>, all handing you back a long. it's giving ✨consistency✨

🦋 DESCRIPTION 🦋

okay so each one of these is basically a different little counter you can vibe-check. here's the rundown, no cap 🌈

  • SSL_CTX_sess_number() — returns the current number of sessions chillin' in the internal session cache. that's the live headcount bestie 💅
  • SSL_CTX_sess_connect() — returns the number of started SSL/TLS handshakes in client mode. started, not finished — we're counting the attempts 🎀
  • SSL_CTX_sess_connect_good() — returns the number of successfully established SSL/TLS sessions in client mode. the ones that actually ate 🔥
  • SSL_CTX_sess_connect_renegotiate() — returns the number of started renegotiations in client mode.
  • SSL_CTX_sess_accept() — returns the number of started SSL/TLS handshakes in server mode. server-side version of the "started" count 👑
  • SSL_CTX_sess_accept_good() — returns the number of successfully established SSL/TLS sessions in server mode.
  • SSL_CTX_sess_accept_renegotiate() — returns the number of started renegotiations in server mode.
  • SSL_CTX_sess_hits() — returns the number of successfully reused sessions ✨ In client mode, a session set with SSL_set_session(3) that gets successfully reused is counted as a hit. In server mode, a session successfully retrieved from the internal or external cache is counted as a hit. hits = the moment the cache came through for you 💖
  • SSL_CTX_sess_cb_hits() — returns the number of successfully retrieved sessions from the external session cache in server mode. external cache W 🫶
  • SSL_CTX_sess_misses() — returns the number of sessions proposed by clients that were not found in the internal session cache in server mode. the flops 😭 (affectionate)
  • SSL_CTX_sess_timeouts() — returns the number of sessions proposed by clients and either found in the internal or external session cache in server mode, but that were invalid due to timeout. and listen — these sessions are not included in the SSL_CTX_sess_hits() count, okay? don't double count, that's not the vibe 🙈
  • SSL_CTX_sess_cache_full() — returns the number of sessions that were removed because the maximum session cache size was exceeded. eviction era 💀

⭐ RETURN VALUES ⭐

the functions return the values indicated in the DESCRIPTION section. that's it, that's the tea ☕ no surprises, no plot twists.
