11 long SSL_CTX_sess_set_cache_size(SSL_CTX *ctx, long t);
12 long SSL_CTX_sess_get_cache_size(SSL_CTX *ctx);
16 SSL_CTX_sess_set_cache_size() sets the size of the internal session cache
17 of context B<ctx> to B<t>.
19 SSL_CTX_sess_get_cache_size() returns the currently valid session cache size.
23 The internal session cache size is SSL_SESSION_CACHE_MAX_SIZE_DEFAULT,
24 currently 1024*20, so that up to 20000 sessions can be held. This size
25 can be modified using the SSL_CTX_sess_set_cache_size() call. A special
26 case is the size 0, which is used for unlimited size.
28 When the maximum number of sessions is reached, no more new sessions are
29 added to the cache. New space may be added by calling
30 L<SSL_CTX_flush_sessions(3)|SSL_CTX_flush_sessions(3)> to remove
33 If the size of the session cache is reduced and more sessions are already
34 in the session cache, old session will be removed at the next time a
35 session shall be added. This removal is not synchronized with the
36 expiration of sessions.
40 SSL_CTX_sess_set_cache_size() returns the previously valid size.
42 SSL_CTX_sess_get_cache_size() returns the currently valid size.
