在django中间件中使用HTTP HttpResponsePermantRedirect时，站点进入重定向循环

当我尝试在Heroku上部署时，我在我的网站上得到了带有此代码的重定向循环。下面是中间件的代码

# -*- coding: utf-8 -*-

from django.utils.functional import SimpleLazyObject
from django.conf import settings
from django.http import HttpResponsePermanentRedirect

def get_country_request(ip):
   import pygeoip
   file_path = settings.PROJECT_ROOT + '/data/GeoIP.dat.dat'
   gi = pygeoip.GeoIP(file_path)
   country = gi.country_name_by_addr(ip)   
   if country:
      return country

class LocationMiddleWare(object):


    def process_request(self, request):
        if 'HTTP_X_FORWARDED_FOR' in request.META:
            request.META['REMOTE_ADDR'] = request.META['HTTP_X_FORWARDED_FOR']
        ip = request.META['REMOTE_ADDR']
        print request.path
        country = get_country_request(ip)             
        if country == "India":
          return HttpResponsePermanentRedirect('/en/')       
        if country == "Netherlands":
          return HttpResponsePermanentRedirect('/nl/')
        return None

请说明我哪里做错了，并说明是否有更好的方法

提前谢谢

你总是在重新引导来自印度和荷兰的人，这是一个循环，因为没有中断。仅当

请求时才应执行重定向。路径
不是
/en/
或
/nl/

def process_request(self, request):
    # NOTICE: This will make sure redirect loop is broken.
    if request.path in ["/en/", "/nl/"]:
        return None
    if 'HTTP_X_FORWARDED_FOR' in request.META:
        request.META['REMOTE_ADDR'] = request.META['HTTP_X_FORWARDED_FOR']
    ip = request.META['REMOTE_ADDR']
    print request.path
    country = get_country_request(ip)             
    if country == "India":
        return HttpResponsePermanentRedirect('/en/')       
    if country == "Netherlands":
        return HttpResponsePermanentRedirect('/nl/')
    return None

非常感谢！你太棒了：）很高兴能帮上忙：）
