Django: What's the correct way to get the requesting IP address?

I'm trying to develop an app using Django 1.1 on Webfaction. I'd like to get the IP address of the incoming request, but when I use request.META['REMOTE_ADDR'] it returns 127.0.0.1. There seems to be a number of different ways of getting the address, such as using HTTP_X_FORWARDED_FOR o开发者_运维问答r plugging in some middleware called SetRemoteAddrFromForwardedFor. Just wondering what the best approach was?

The remote proxy middleware was removed in Django 1.1.1 with a nod towards pointing out that trusting REMOTE_ADDR or HTTP_X_FORWARDED for isn't secure anyway (in case that also helps you decide what to do)

I use the middleware because this way I don't have to change the app's code.

If I want to migrate my app to other hosting servers, I only need to modify the middleware without affecting other parts.

Security is not an issue because on WebFaction you can trust what comes in from the front end server.
