SSL_CTX_SESS_SET_CACHE_SIZE(3OpenSSSSL_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);
DESCRIPTIONSSL_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 ses-
sions.
If the size of the session cache is reduced and more ses-
sions 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 VALUESSSL_CTX_sess_set_cache_size() returns the previously valid
size.
SSL_CTX_sess_get_cache_size() returns the currently valid
size.
