Topic: Route not Working in Production Environment

I have  very add problem that I have spend almost 2 days.
I am running the same application on 2 machines in development and
production environment.
The problem is that a route in production don't work.
If I type "rake routes" I get exactly the same result on both
machines.
The route that does not work is  a map.resource route and I am running
thin web server.
Am I missing some conf, please help I am going insane !!

My assumption is that the HTTP request is not handled properly.
