How to retrieve remote port in Django

Question

I am writing a web server script and need remote port from which a client connected. Is there any way I may retrieve it? I am using django framework for development.

ADDED:

When a client sends a HTTP Request, there would be one source TCP port at the machine, which would be modified in NAT process. Finally, SYN (TCP) to web server would be from, say port P1. I need that port P1 from which the web server receives a connection request.

Now in HttpRequest meta dict, I was not able to see it. Is there any other way?

Answer 1

This does not seem possible with only Django, however if you run it on top of Apache and mod_wsgi you can then access it from a request object by request.META['REMOTE_PORT']

Answer 2

The destination (server) port is included in the request's meta dictionary.

def get_port(request):
    if 'SERVER_PORT' in request.META:
        return request.META['SERVER_PORT']
    else:
        return None

The source port will not be accessible at the application layer of the TCP/IP stack.
