What happens to the request after it is processed in…

After processing by a view (function or class method), the following occurs:

Formation of an HttpResponse. The view returns an HttpResponse object. This object contains the response body (e.g., HTML, JSON), status code (e.g., 200 OK, 404 Not Found), and headers (e.g., Content-Type).
Processing by middleware. The HttpResponse object passes through outgoing middleware in reverse order compared to incoming middleware. Each middleware can modify the response or perform additional actions (e.g., add security headers).
Returning the response to the web server. The formed HttpResponse, after middleware processing, is passed back to the web server (e.g., Gunicorn, uWSGI), which sent the request. The web server then sends this response to the client (browser or other application) that initiated the request.

# Example of returning an HttpResponse in a view
from django.http import HttpResponse

def my_view(request):
    # Request processing
    return HttpResponse("Hello, World!", status=200, content_type="text/plain")

# Example middleware that modifies the response
# settings.py
# MIDDLEWARE = [
#     'path.to.MyMiddleware',
#     # ... other middleware
# ]

# my_app/middleware.py
from django.utils.deprecation import MiddlewareMixin

class MyMiddleware(MiddlewareMixin):
    def process_response(self, request, response):
        # Adding a header to the response
        response['X-Custom-Header'] = 'Processed'
        return response
