NAME
SSL_CTX_sess_set_cache_size, SSL_CTX_sess_get_cache_size - manipulate session cache size
LIBRARY
libcrypto, -lcrypto
SYNOPSIS
#include
long SSL_CTX_sess_set_cache_size(SSL_CTX *ctx, long t);
long SSL_CTX_sess_get_cache_size(SSL_CTX *ctx);
DESCRIPTION
_S_S_L___C_T_X___s_e_s_s___s_e_t___c_a_c_h_e___s_i_z_e_(_) sets the size of the internal session cache
of context ccttxx to tt.
_S_S_L___C_T_X___s_e_s_s___g_e_t___c_a_c_h_e___s_i_z_e_(_) 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 _S_S_L___C_T_X___s_e_s_s___s_e_t___c_a_c_h_e___s_i_z_e_(_) 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
_S_S_L___C_T_X___f_l_u_s_h___s_e_s_s_i_o_n_s(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
_S_S_L___C_T_X___s_e_s_s___s_e_t___c_a_c_h_e___s_i_z_e_(_) returns the previously valid size.
_S_S_L___C_T_X___s_e_s_s___g_e_t___c_a_c_h_e___s_i_z_e_(_) returns the currently valid size.
