150The internal session cache size is \s-1SSL_SESSION_CACHE_MAX_SIZE_DEFAULT\s0,
984263bc
MD
151currently 1024*20, so that up to 20000 sessions can be held. This size
152can be modified using the \fISSL_CTX_sess_set_cache_size()\fR call. A special
153case is the size 0, which is used for unlimited size.
154.PP
155When the maximum number of sessions is reached, no more new sessions are
156added to the cache. New space may be added by calling
e056f0e0 157\&\fISSL_CTX_flush_sessions\fR\|(3) to remove
984263bc

158expired sessions.
159.PP
160If the size of the session cache is reduced and more sessions are already
161in the session cache, old session will be removed at the next time a
162session shall be added. This removal is not synchronized with the
163expiration of sessions.
