-=head1 NAME
-
-SSL_CTX_sess_set_cache_size, SSL_CTX_sess_get_cache_size - manipulate session cache size
-
-=head1 SYNOPSIS
-
- #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);
-
-=head1 DESCRIPTION
-
-SSL_CTX_sess_set_cache_size() sets the size of the internal session cache
-of context B<ctx> to B<t>.
-This value is a hint and not an absolute; see the notes below.
-
-SSL_CTX_sess_get_cache_size() returns the currently valid session cache size.
-
-=head1 NOTES
-
-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.
-
-If adding the session makes the cache exceed its size, then unused
-sessions are dropped from the end of the cache.
-Cache space may also be reclaimed by calling
-L<SSL_CTX_flush_sessions(3)|SSL_CTX_flush_sessions(3)> to remove
-expired sessions.
-
-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.
-
-=head1 RETURN VALUES
-
-SSL_CTX_sess_set_cache_size() returns the previously valid size.
-
-SSL_CTX_sess_get_cache_size() returns the currently valid size.
