+=head1 NAME
+
+SSL_CTX_set_timeout, SSL_CTX_get_timeout - manipulate timeout values for session caching
+
+=head1 SYNOPSIS
+
+ #include <openssl/ssl.h>
+
+ long SSL_CTX_set_timeout(SSL_CTX *ctx, long t);
+ long SSL_CTX_get_timeout(SSL_CTX *ctx);
+
+=head1 DESCRIPTION
+
+SSL_CTX_set_timeout() sets the timeout for newly created sessions for
+B<ctx> to B<t>. The timeout value B<t> must be given in seconds.
+
+SSL_CTX_get_timeout() returns the currently set timeout value for B<ctx>.
+
+=head1 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
+L<SSL_SESSION_get_time(3)|SSL_SESSION_get_time(3)> family of functions.
+
+Expired sessions are removed from the internal session cache, whenever
+L<SSL_CTX_flush_sessions(3)|SSL_CTX_flush_sessions(3)> is called, either
+directly by the application or automatically (see
+L<SSL_CTX_set_session_cache_mode(3)|SSL_CTX_set_session_cache_mode(3)>)
+
+The default value for session timeout is 300 seconds.
+
+=head1 RETURN VALUES
+
+SSL_CTX_set_timeout() returns the previously set timeout value.
+
+SSL_CTX_get_timeout() returns the currently set timeout value.
