Bitrix, php, how to catch the end of the session?

Question

1C-Bitrix

You need to set a cookie at the end of the session

setcookie("emailUser", 'null', time()+60*60*24*30, "/");

How to catch the end of the session (for example, in Bitrix, the session is 24 minutes, after which the user is deauthorized. The standard Bitrix events of the OnBeforeUserLogout and OnAfterUserLogout types work only if the deauthorization occurs through LogOut (), and I need to catch the moment the session ends.)?

Answer 1

So just don't catch it. php scripts work on requests. As long as the user does nothing, then nothing will be passed to the user.
