Out of curiosity, how do you inject your own request_handler if you are running behind something like uwsgi/nginx where you only specify the wsgi container and don't ever call run yourself? It appears the request_handler is only passed on through to werkzeug via run(kwargs).

You don't, he just hacked the development server Flask uses, you shouldn't use it in production anyway.

The better and more general approach would be using a WSGI middleware.
