Disabling Passenger built-in error handler

Overview

Passenger provides a user-friendly, on-screen error handler to assist debugging a Python/Ruby/Node.js application. During production, however, this may result in unnecessary and possibly dangerous information disclosure. You can turn off Passenger’s built-in logger and use Apache’s generic error handler by adding the following line to your .htaccess file located within the public/ folder of your app:

PassengerErrorOverride On

Errors can then be viewed through /var/log/httpd/passenger.log
