SSL_CTX_SET_TIMEOUT(3)		    OpenSSL		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.
