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.
