This constant must be initialized before prolog inside files-handlers of 404 error (page not found). Such handler files are specified in the web server settings.

Initializing this constant allows changing page that receives a corresponding submitted form in standard components for authorization, registration, forgotten password resend and password change. This page by default is the current page, however, if the constant is initialized, it will be - /SITE_DIR/auth.php.

The requirement to initialize this constant is related to the fact you cannot send data by POST method to non-existing pages. But specifically this method is employed by the abovementioned components. That's why if the file for the current page physically doesn't exist on the server, component won't work without it.
