Wsgi.py - why is it created at startproject?

Question

Django

Subject - I don’t understand why it is needed and I can’t find where to read
in an easily accessible form about this
innovation, from some version.

Answer 1

With it, the application can work with a web server (Nginx, Apache, and many others) using the WSGI protocol. Here it is written about the protocol, and here and here how to apply it in Django.

Answer 2

This code defines the wsgi application in the application variable. In fact, django doesn't true-wsgi.
