Hi all

Is there a way to capture the domain name and form there open one  
application or another.

I have to domains registered. domain1 and domain2

Is there a way when someone types [www.domain1.com](http://www.domain1.com) it calls a RoR page  
that allows me to redirect the person to a specific application or to a  
specific domain?

thanks
