SSL_CTX_set_timeout(3)17/Aug/2001 (0.9.7e) SSL_CTX_set_timeout(3)
NAME
SSL_CTX_set_timeout, SSL_CTX_get_timeout - manipulate
timeout values for session caching
SYNOPSIS
#include <openssl/ssl.h>
long SSL_CTX_set_timeout(SSL_CTX *ctx, long t);
long SSL_CTX_get_timeout(SSL_CTX *ctx);
DESCRIPTION
SSL_CTX_set_timeout() sets the timeout for newly created
sessions for ctx to t. The timeout value t must be given in
seconds.
SSL_CTX_get_timeout() returns the currently set timeout
value for ctx.
NOTES
Whenever a new session is created, it is assigned a maximum
lifetime. This lifetime is specified by storing the creation
time of the session and the timeout value valid at this
time. If the actual time is later than creation time plus
timeout, the session is not reused.
Due to this realization, all sessions behave according to
the timeout value valid at the time of the session
negotiation. Changes of the timeout value do not affect
already established sessions.
The expiration time of a single session can be modified
using the SSL_SESSION_get_time(3) family of functions.
Expired sessions are removed from the internal session
cache, whenever SSL_CTX_flush_sessions(3) is called, either
directly by the application or automatically (see
SSL_CTX_set_session_cache_mode(3))
The default value for session timeout is decided on a per
protocol basis, see SSL_get_default_timeout(3). All
currently supported protocols have the same default timeout
value of 300 seconds.
RETURN VALUES
SSL_CTX_set_timeout() returns the previously set timeout
value.
SSL_CTX_get_timeout() returns the currently set timeout
value.
