mORMot Open Source

Hi,

I want to host 2 services, a mORMOT server and a blog in Java on my rapsberry pi 2 server. (Yes, the REST Server works! Awesome!)
To do this, i use nginx to redirect request:
   http://localhost/  => redirect to localhost:9000 (java app)
   http://localhost/app => redirect to localhost:8080 mormot REST Server

So i set up nginx to redirect request with proxy_pass (see config below). The redirection works when i access with my browser to http://localhost:8080/root/index, i see my page. But when I access to http://localhost/root/index, it takes 5 second to show the page. It seems, that it's Nginx which take time to redirect the url. Here the nginx config I use.
Does someone know how to redirect mormot url with nginx?

Thanks.
