Redmine

Hello there,
with this configuration:

upstream local_thin_cluster {
    server 127.0.0.1:3000;
    server 127.0.0.1:3001;
}

server {
    #listen   80;

    access_log /usr/share/redmine/log/nginx_access.log;
    error_log  /usr/share/redmine/log/nginx_error.log;

    root    /usr/share/redmine/public;
    proxy_redirect  off;

    location / {
        proxy_set_header  X-Real-IP  $remote_addr;
        proxy_set_header  X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header  Host $http_host;

        try_files $uri $uri/index.html $uri.html @cluster;
    }

    location @cluster {
        proxy_pass http://local_thin_cluster ;
    }
}

The problem I have is that after login redirection in redmine I get the address http://local_thin_cluster/my/page. It works OK if I access thin server via port directly.

Could anybody help ?
