Question

As the title described, Django keeps changing my URL from /localhost/ to /127.0.0.1:8080/ which keeps messing up my serving static files by Nginx. Any ideas why its doing this? Thanks!

/**EDIT**/
Here is the Nginx configuration:

server {

    listen   80; ## listen for ipv4
    listen   [::]:80 default ipv6only=on; ## listen for ipv6

    server_name  localhost;

    access_log  /var/log/nginx/localhost.access.log;

    location ~* ^.+\.(jpg|jpeg|gif|png|ico|css|zip|tgz|gz|rar|bz2|pdf|txt|tar|wav|bmp|rtf|js|flv|swf|html|htm)$
    {
            root   /srv/www/testing;
    }

    location / {
            proxy_pass         http://127.0.0.1:8080/;
            proxy_redirect     off;
    }

    location /doc {
        root   /usr/share;
        autoindex on;
        allow 127.0.0.1;
        deny all;
    }

    location /images {
        root   /usr/share;
        autoindex on;
    }

Here is Apache config file:

<VirtualHost *:8080>

    ServerName testing
    DocumentRoot /srv/www/testing

    <Directory /srv/www/testing>
        Order allow,deny
        Allow from all
    </Directory>

    WSGIScriptAlias / /srv/www/testing/apache/django.wsgi

</VirtualHost>

What I think is happening is when you use your httpresponseredirect, the HTTP_HOST header is giving it the 127.0.0.1:8080, because of your proxy_pass setting.

Django's HttpResponseRedirect seems to strip off my subdomain?

Django has some methods it always
applies to a response. One of these is
django.utils.http.fix_location_header.
This ensures that a redirection
response always contains an absolute
URI (as required by HTTP spec).
