I am trying to setup nginx with a reverse proxy to tracd, however I only want to use 1 tracd.

Now first here's my config for this domain

server {
    listen   80;
    server_name bugs.XXXXXXXX.com;

    access_log  /var/log/nginx/XXXXXXXX-bugtracker.access.log proxy;

    location / {
        rewrite ^/bugtracker/(.*)$ /$1;
        rewrite ^/bugtracker$ /;
        proxy_pass http://127.0.0.1:81/bugtracker/;
        proxy_redirect default;
        proxy_set_header Host $host;
    }

    location ~ /\.ht {
        deny  all;
    }
}

As you can see there's the rewrite rules, because for some reason all the urls that tracd spews out are like /bugtracker/something.

Now this is indeed caused by tracd just sending urls like it normally should however trac is at bugs.XXXXXXXX.com/ and not at bugs.XXXXXXXX.com/bugtracker. So how can I make tracd/trac display the (In this case) correct urls ?
