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:…

Overview Python applications can be launched using Passenger offering improved throughput and lifecycle management. Launching CGI scripts wrapped by pyenv will yield very poor throughput as a result of multiple shell subprocesses necessary to ascertain the correct Python interpreter. Adapting a CGI application to WSGI improves throughput significantly by reducing overhead through a persistent process. Pages load quickly, and applications utilize…
