Redirect user based on url entered?

Rails
1

Let’s say a user entered this url into the browser:

http://www.something.com/blarblar

how do i redirect the user to the index/main page if i don’t have a
blarblar controller?
basically i want to check for invalid urls passed in by user and
redirect them to the correct url/page~
any ideas? thanx !
