What are the different types of middleware in Django?

Django middleware is a framework of hooks into Django's request/response processing. There are several types, including:

1. Common Middleware: Handles tasks like URL rewriting and session management.
2. Session Middleware: Manages user sessions across requests.
3. Authentication Middleware: Associates users with requests using sessions.
4. Message Middleware: Enables temporary messages to be stored in the session.
5. CORS Middleware: Handles Cross-Origin Resource Sharing for APIs.

Can you explain how session middleware works?

Session middleware in Django manages user sessions by storing session data on the server side and sending a session ID to the client as a cookie. This allows the server to identify returning users and maintain state across requests.

What is the purpose of authentication middleware?

Authentication middleware is responsible for associating users with requests. It checks if a user is authenticated and adds the user object to the request, allowing views to access user information easily.

Are there any custom middleware examples?

Yes, you can create custom middleware to perform specific tasks, like logging requests, modifying responses, or handling errors. You just need to define a class with methods like __init__, __call__, and process_request.
