此网页有重定向循环？

Question

我想根据请求的IP将请求重定向到相应的URL。为此，我正在编写一个中间件。

from django.contrib.gis.geoip import GeoIP
from teashop import settings as settings
from django.http import HttpResponseRedirect

# IPs for Testing
# Indian IP : '182.75.107.138'
# Russian IP : '95.108.142.138'
# Chinese IP : '27.227.255.255'


class GeoRedirectionMiddleware(object):


    def process_request(self, request):
        """
        Detect Location using GeoIP
        """ 
        g = GeoIP()
        ip = '95.108.142.138'
        country_dict = g.country(ip)
        if country_dict["country_code"] == "RU":
           if '/ru' not in request.path:
              return HttpResponseRedirect('/ru'+request.path)
           else:
              pass

这会将'/'重定向到'/ru/'。但是，当我访问其他网址'/abc'时，它会显示太多重定向。
