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

[http://www.something.com/blarblar](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 !
