Have you had experience integrating custom middleware into your system?

Yes, experience with integrating custom middleware into a system is common, especially in web development with Python.

Middleware are components that handle requests and responses between the client and server, allowing for added functionality such as logging, authentication, and error handling.

An example of simple middleware in Django:

class SimpleMiddleware:
    def __init__(self, get_response):
        self.get_response = get_response

    def __call__(self, request):
        print(f"Request: {request.path}")  # Log the request path
        response = self.get_response(request)
        print(f"Response: {response.status_code}")  # Log the response status
        return response

This middleware can be added to the project settings and will be automatically invoked on each request.
