Method not found > Error page

Hey,
I was wondering. If someone travels to a url ie.
app.com/controller/method

and method does not exist. How do i present them with a page not found
error instead of getting Rails method not found errors?

thanks,
bp

Read about routes. I'm not an expert but I remember reading about
being able to set a default 'catch all' to redirect wherever you want.
