Question

How do I render a 404 or page doesn’t exist like Twitter does?
I use rails 3.2.3

My code

def rescue_with_handler(exception)
  redirect_to '/500.html'
end

def method_missing(id, *args)
 redirect_to '/404.html'
end

That works, but I want to be like twitter. For example if I access this page
https://twitter.com/abcd/skka/asafaga
and https://twitter.com/abcd/skka
