Force rerender the page after redirect 302 (not from browser cache)

browser will load the page from local cache if redirect with 302 to the page which is already saved in cache. e.g. set language function

solution is to add ? parameter to the url to force reload

    def get(self, request):
        language_code = request.GET.get("lang", settings.LANGUAGE_CODE)
        return_url = request.GET.get("next", "/home/")
        if return_url.find('?') != -1:
            return_url = return_url[:return_url.find('?')]
        translation.activate(language_code)
        request.session[translation.LANGUAGE_SESSION_KEY] = language_code
        request.session.modified = True
        # print(request.build_absolute_uri(return_url))
        return HttpResponseRedirect(request.build_absolute_uri(return_url) + '?setlanguage=' + str(time.time()))
