### Middleware
from django.conf import settings
from django.utils import translation
from django.http import Http404

class I18nUrlsMiddleware(object):
	"""
	This is a very simple middleware that checks if the view being requested
	is about to receive a "dj_culture" parameter. If this is the case, this 
	middleware removes this argument and uses it to initialize Django's
	i18n system with the requested culture if it is one of the supported
	cultures.
	"""
	
	def handle_culture(self,request,culture):
		translation.activate(culture)
		request.LANGUAGE_CODE = translation.get_language()
	
	def process_view(self, request, view_func, view_args, view_kwargs):
		culture = view_kwargs.get('dj_culture',None)
		if culture:
			ret = None
			if culture in settings.CULTURES:
				ret = self.handle_culture(request,culture)
			else:
				# Fallback for the lazy of us who prefer to keep things simple.
				pcult = culture.split('-')[0]
				if pcult in settings.CULTURES:
					ret = self.handle_culture(request,pcult)
				else:
					raise Http404
			# Remove the culture parameter again so that we can use all our
			# old views.
			del(view_kwargs['dj_culture'])
			return ret

### URLs
from django.conf.urls.defaults import *

urlpatterns = patterns('',
	(r'(?P<dj_culture>[\w-]+)/','views.index'),
)

Very useful snippet - Django's handling of i18n is great, but sometimes it's nice to be able to specify the language code in the URL.
