SSL_CTX_sess_set_cache_size(3)
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
  The SSL_CTX_sess_set_cache_size() function sets the size of the internal
  session cache of context ctx to t.

  The SSL_CTX_sess_get_cache_size() function 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 20,000 sessions can be held.	 This size
  can be modified using the SSL_CTX_sess_set_cache_size() function. A special
  case is the size 0, which is used for unlimited size.

  When the maximum number of sessions is reached, no new sessions are added
  to the cache. New space may be added by calling the
  SSL_CTX_flush_sessions() function to remove expired sessions.

  If the size of the session cache is reduced and more sessions are in the
  session cache, an old session will be removed when a new session is added.
  This removal is not synchronized with the expiration of sessions.

RETURN VALUES
  The SSL_CTX_sess_set_cache_size() function returns the previously valid
  size.

  The SSL_CTX_sess_get_cache_size() function returns the currently valid
  size.
