升级到Django 1.5后,我开始收到这样的错误:

Traceback (most recent call last):

昨晚我部署了我的Django应用程序后,我收到了大量奇怪的电子邮件说:

ERROR: Invalid HTTP_HOST header: '/webapps/example_com/run/gunicorn.sock

我确定这与以下nginx配置有某种关系:

upstream example_app_server {
  server unix:/webapps/example_com/run/gunicorn.sock fail_timeout=0;
}

server {

    listen   80;
    server_name example.com;

    client_max_body_size 4G;

    access_log /webapps/example_com/logs/nginx-access.log;
    error_log /webapps/example_com/logs/nginx-error.log;


    location / {
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

        proxy_set_header Host $http_host;

        proxy_redirect off;

        if (!-f $request_filename) {
            proxy_pass http://example_app_server;
            break;
        }
    }
}

我有一个域名的网站www.example1.com，最近我已经指出另一个域DNSwww.example2.com到包含www.example1.com同一台服务器，这样既www.example1.com和www.example2.com服务相同的代码，但域名应该是不同的，我想从Django的请求获得域名如下

def homepage(request):
    domain = request.META['HTTP_HOST']
    if domain == 'www.example1.com':
       return HTTPResponseReredirect('/new/')
    elif domain == 'www.example2.com':
       return HTTPResponseReredirect('/old/')

所以基于域名，我想将用户重定向到不同的网页，但每次我使用request.META['HTTP_HOST']输出时都是一个 IP 地址127.0.0.1:8001，如下所示
