       SSL_CTX_sess_set_cache_size, SSL_CTX_sess_get_cache_size - manipulate session cache size

	#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);

       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.

       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

       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.

       SSL_CTX_sess_set_cache_size() returns the previously valid size.

       SSL_CTX_sess_get_cache_size() returns the currently valid size.
