Django get client's domain name/host name
You can just print HttpRequest.META and find what you want and I think req.META['HTTP_ORIGIN'] is the thing you need, It's the same as the browser address bar value.
What is the easiest way to obtain the user's host/domain name, if available?
Or is there a function to lookup the IP address of the user to see if it is bound to a named address? (i.e. gethostbyaddr() in PHP)
HttpRequest.get_host() only returns the IP address of the user.
