Django i18n pattern

Question

I'm using internationalization.

So, everyhting works fine, when I access http://localhost:8000/en/ and http://localhost:8000/de/

But when I access http://localhost:8000/ it redirects me to http://localhost:8000/en/ even when the last accessed page was http://localhost:8000/de/

Basically, I want to save language code, based on the page accessed, e.g. if I access http://localhost:8000/de/ then language is german. Next, when I access http://localhost:8000, it should point me to http://localhost:8000/de/, not default http://localhost:8000/en/

How this can be done?

The issue was that Django didn't add request.session['django_language'] = lang_code

I just extend locale middleware and use the following code.

def process_request(self, request):

    if self.is_language_prefix_patterns_used():
        lang_code = (get_language_from_path(request.path_info) or
                     request.session.get('django_language', settings.LANGUAGE_CODE))

        activate(lang_code)
        request.session['django_language'] = lang_code
        request.LANGUAGE_CODE = get_language()

Now, I have following question. What should I do so that http://localhost:8000 didn't redirect (to prefix with language code)?

I found following code:

class NoPrefixLocaleRegexURLResolver(LocaleRegexURLResolver):

@property
def regex(self):
    language_code = get_language()
    if language_code not in self._regex_dict:
        regex_compiled = (re.compile('' % language_code, re.UNICODE)
                          if language_code == settings.LANGUAGE_CODE
                          else re.compile('^%s/' % language_code, re.UNICODE))

        self._regex_dict[language_code] = regex_compiled
    return self._regex_dict[language_code]

However, there is problem with that code in checking if language_code == settings.LANGUAGE_CODE. If I enter http://localchost:8000, it will not redirect, but supply a page with translation from settings.LANGUAGE_CODE instead of request.session.get('django_language'). As I understood, I can't access request, so what should be done?
