ssl_ctx_sess_set_cache_size(3)
NAME
SSL_CTX_sess_set_cache_size, SSL_CTX_sess_get_cache_size - manipulate
session cache size
SYNOPSIS
#include <openssl/ssl.h> long SSL_CTX_sess_set_cache_size(SSL_CTX *ctx, long t); long SSL_CTX_sess_get_cache_size(SSL_CTX *ctx);
DESCRIPTION
SSL_CTX_sess_set_cache_size() sets the size of the internal session
cache of context ctx to t.
SSL_CTX_sess_get_cache_size() returns the currently valid session cache
size.
NOTES
The internal session cache size is SSL_SESSION_CACHE_MAX_SIZE_DEFAULT,
currently 1024*20, so that up to 20000 sessions can be held. This size
can be modified using the SSL_CTX_sess_set_cache_size() call. A special
case is the size 0, which is used for unlimited size.
When the maximum number of sessions is reached, no more new sessions
are added to the cache. New space may be added by calling
SSL_CTX_flush_sessions(3) to remove expired sessions.
If the size of the session cache is reduced and more sessions are
already in the session cache, old session will be removed at the next
time a session shall be added. This removal is not synchronized with
the expiration of sessions.
RETURN VALUES
SSL_CTX_sess_set_cache_size() returns the previously valid size.
SSL_CTX_sess_get_cache_size() returns the currently valid size.
