Starts the app listening on localhost, for local development.

This script launches the Django and Tornado servers, then runs a reverse proxy
|
|
which serves to both of them. After it's all up and running, browse to
|
|
|
|
http://localhost:9991/
|
|
|
|
Note that, while runserver and runtornado have the usual auto-restarting
|
|
behavior, the reverse proxy itself does *not* automatically restart on changes
|
|
to this file.
