Forcing Nginx to render response from Rails application

[retro]

Hi, I'm using Nginx with Phusion Passenger, and I would like to render some responses from Rails App even though file exists at that URI on server. I want to do this based on subdomain from which request is coming. Is something like that even possible? I've managed to do redirect based on this conditions but it would be better if I could do that internally, without change to URL.
