Question : Rails: How do I get the domain name

Is there an easy way to get the domain name of where something was called from?

For example, if I have the same app that is linked to both www.somesite.com and www.somesite.net, is there an easy way to find out which one the user is clicking through to use the app?

Thanks,
Grant
