157.IX Header "NOTES"
158The internal session cache size is \s-1SSL_SESSION_CACHE_MAX_SIZE_DEFAULT\s0,
984263bc
MD
159currently 1024*20, so that up to 20000 sessions can be held. This size
160can be modified using the \fISSL_CTX_sess_set_cache_size()\fR call. A special
161case is the size 0, which is used for unlimited size.
162.PP
163When the maximum number of sessions is reached, no more new sessions are
164added to the cache. New space may be added by calling
e056f0e0 165\&\fISSL_CTX_flush_sessions\fR\|(3) to remove
984263bc
MD
166expired sessions.
167.PP
168If the size of the session cache is reduced and more sessions are already
169in the session cache, old session will be removed at the next time a
170session shall be added. This removal is not synchronized with the
171expiration of sessions.
