Doubt about Sessions in the IC

Question

According to :

$config['sess_expiration'] = 7200;

The session will be destroyed after 7200 seconds, however I wanted to know if when I update the page or access another page of my system, that time is renewed ? If not, is there any configuration in the IC config that does this ?

$config['sess_time_to_update'] = 300;

'sess_time_to_update'
|
|   How many seconds between CI regenerating the session ID.

What would be this regeneration/renewal of the Session id ?

There is a correlation in the two questions where $config['sess_time_to_update'] means the frequency of the session update, and every 5 minutes this occurs (default setting), generating a new ID session and reset the session expiration expiration setting based on the key $config['sess_expiration'].

Usually we configure otherwise:

$config['sess_expiration']  = 0;
$config['sess_expire_on_close'] = TRUE;

where the 'sess_expiration' configured with 0 and 'sess_expire_on_close' with the value TRUE, meaning that the session is only destroyed when the user closes the browser or via encoding with user intervention, particularly do so and never had problems.
