Setting rails root

Hi there,

I was running a RoR app on a domain such as http://www.somedomain.com
using the Mongrel server. I have now moved the app to a host that has
the following requirements.

The RoR app resides outside of public_html folder with a symlink to a
folder inside the public_html folder. The other thing is instead of
accessing the site via a URL such as: http://www.somedomain.com it
runs as follows:
somedomain.com

The new host also uses FastCgi as apposed to Mongrel. The controllers
and actions are not working on this new environment. Is this a
configuration option or what else might I be missing.

Regards,
Schalk
