16 SSL_CTX_sess_set_cache_size() sets the size of the internal session
17 cache of context ctx to t.
18
19 SSL_CTX_sess_get_cache_size() returns the currently valid session cache
20 size.
21
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.
27
28 When the maximum number of sessions is reached, no more new sessions
29 are added to the cache. New space may be added by calling
30 SSL_CTX_flush_sessions(3) to remove expired sessions.
31
32 If the size of the session cache is reduced and more sessions are
33 already in the session cache, old session will be removed at the next
34 time a session shall be added. This removal is not synchronized with
35 the expiration of sessions.
36
38 SSL_CTX_sess_set_cache_size() returns the previously valid size.
39
40 SSL_CTX_sess_get_cache_size() returns the currently valid size.
