~~~~~~~~~~~~~~~~~~~~~

|
|
|
||
|
|
This module provides the WSGI application.
|
||
|
|
|
||
|
|
The WSGI middlewares are applied in the `make_app` factory function
|
||
|
|
that automatically wraps the application within the require
|
||
|
|
middlewares. Per default only the `SharedDataMiddleware` is applied.
