nginx subdomain and domain rewrite w proxy pass - django

Question

I need these two types of rewrites:
subdomain.domain.com => domain.com/website/subdomain
otherdomain.com => domain.com/userdomain/otherdomain.com
My problem is that I want the user to see subdomain.domain.com, and otherdomain.com, not the redirected version. My current rewrite in nginx works, but the user's URL shows the rewrite, and I want this to be transparent to the user, any ideas?:
upstream domain_server { server localhost:8000 fail_timeout=0; }
server {
listen 80;
root /var/www/domain.com;
server_name domain.com ~^(?<subdomain>.*)\.domain\.com$ ~^(?<otherdomain>.*)$;
if ( $subdomain ) {
rewrite ^ http://domain.com/website/$subdomain break;
}
if ( $otherdomain ) {
rewrite ^ http://domain.com/userdomain/$otherdomain break;
}
location / {
proxy_redirect off;
proxy_buffering off;
proxy_set_header Host $http_host;
proxy_set_header X-forwarded-for $proxy_add_x_forwarded_for;
if (!-f $request_filename) {
proxy_pass http://domain_server;
break;
}
}
}

With nginx you don't need rewrites at all.
upstream domain_server { server localhost:8000 fail_timeout=0; }
proxy_set_header Host domain.com;
proxy_set_header X-forwarded-for $proxy_add_x_forwarded_for;
server {
listen 80 default_server;
location / {
proxy_pass http://domain_server/userdomain/$http_host;
}
}
server {
listen 80;
server_name domain.com;
root /var/www/domain.com;
location / {
try_files $uri #backend;
}
location #backend {
proxy_pass http://domain_server;
}
}
server {
listen 80;
server_name ~^(?<subdomain>.+)\.domain\.com$;
location / {
proxy_pass http://domain_server/website/$subdomain$request_uri;
}
}
