SSL_CTX_sess_set_cache_size(3)                     OpenSSL                    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.
