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.
