How does a Django project handle incoming requests passing through a proxy server?

When a Django project receives a request through a proxy server (for example, Nginx or Apache), the proxy forwards the HTTP request to the Django application, usually via the WSGI or ASGI interface.

Key points of processing:

• The proxy accepts the external request and may modify headers (for example, adding X-Forwarded-For for the client's IP).
• The proxy redirects the request to an internal address where the Django application is running.
• Django receives the request through a WSGI/ASGI server (such as Gunicorn, Daphne, etc.).
• In Django, the request is processed as usual: URL routing, middleware, view.

It is important to properly configure Django to work behind a proxy, for example, by setting USE_X_FORWARDED_HOST or using django.middleware.security.SecurityMiddleware for correct header processing.
