     NAME
          SSL_CTX_sess_set_cache_size, SSL_CTX_sess_get_cache_size -
          manipulate session cache size

     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);

     DESCRIPTION
          SSL_CTX_sess_set_cache_size() sets the size of the internal
          session cache of context ctx to t.

          SSL_CTX_sess_get_cache_size() returns the currently valid
          session cache size.

     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.

          When the maximum number of sessions is reached, no more new
          sessions are added to the cache. New space may be added by
          calling 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.

     RETURN VALUES
          SSL_CTX_sess_set_cache_size() returns the previously valid
          size.

          SSL_CTX_sess_get_cache_size() returns the currently valid
          size.
