Sinergis is unable to serve under a directory

[mdamt]

Scenario:

A server is set to serve a sinergis site under a directory. E.g. http://host/app is mapped into http://localhost:3000/. In current condition, everything is redirected to /, e.g accessing http://host/app is redirected to http://host/login and not http://host/app/login.

Preliminary code: https://github.com/mdamt/sinergis/tree/underdir

It needs prefix configuration in policy.

What's working:

• login
• redirection to login page

nginx example config:

  location /app {
    rewrite ^/app(/.*)$ $1 break;
    proxy_pass http://127.0.0.1:4000/;
  }
