How can I create a Rails 3 route that will match all requests and direct to one resource / page?

Question

I have a rails app (Rails 3.0) that I need to temporarily take out of service. While this is in effect, I want to create a new route that will direct all requests to a single pi

I did this just yesterday and first came up with the solution that klochner shows. What I didn't like about this is the fact that whatever you enter in the URL, stays there after the page loads, and since I wanted a catch all route that redirects to my root_url, that wasn't very appealing.

What I came up with looks like this:

# in routes.rb
get '*ignore_me' => 'site#unknown_url'

# in SiteController
def unknown_url
  redirect_to root_url
end

Remember to stick the routes entry at the very bottom of the file!

EDIT: As Nick pointed out, you can also do the redirect directly in the routes file.
