As we are running a multilingual website we needed an easy way to place links around the web. Like we would like to put a link on a forum for translators so that they can find our eKe Translation Project Management software, but when they arrice on our site they get to the page with their request.LANGUAGE_CODE. This could be easily achieved with a simple middleware presented below.

from feincms.module.page.models import Page
from django.http import HttpResponseRedirect, Http404
from django.conf import settings

class LanguageLookupMiddleware(object):
    '''
    Redirect to a language specific page if it exists. First look up the request's 
    language, then the default language.
    '''
    def process_response(self, request, response):
        if response.status_code != 404:
            return response # No need to check for a flatpage for non-404 responses.

try:
            language = [short for short, long in settings.LANGUAGES if short==request.LANGUAGE_CODE][0]
        except KeyError:
            pass
        else:
            response = self.get_page(language, request.path) and \
                HttpResponseRedirect('/%s%s' % (language, request.path)) or response

if response.status_code == 404:
            response = self.get_page(settings.LANGUAGES[0][0], request.path) and \
                HttpResponseRedirect('/%s%s' % (settings.LANGUAGES[0][0], request.path)) or \
                response
        return response

def get_page(self, language, path):
        try:
            return Page.objects.page_for_path_or_404('/%s%s' % (language, path))
        except Http404:
            return False

What this middleware does? First it checks for a page request.LANGUAGE_CODE + request.path. If nothing is found then moves on and redirects you to settings.LANGUAGES[0][0] + request.path or gives a 404 error if the page does not exist.
