Rails: redirect all unknown routes to root_url

Whenever a user hits the wrong page, rails shows 404.html from the public folder. However, I'd like just to redirect the browser to the root page, without showing anything. So I tried globbing, but came to no avail, it still shows the 404 page. Here's an extract from my routes file:

# ...
map.root :controller => 'home', :action => 'home'
map.connect '*', :controller => 'home', :action => 'home'

Any suggestions? Thanks, guys!

If your project is powered by rails 3, add simply this line to your routes.rb

match '*path' => redirect('/')

Edit: If you're on Rails 4 or 5

match '*path' => redirect('/'), via: :get

or

get '*path' => redirect('/')

Like the answer by Arkan. One point, if do not want this behaviour in development environment, then could do -

match '*path' => redirect('/')   unless Rails.env.development?

Rails 4-

(routes.rb)

You can still use a simple get to redirect all unknown routes.

  get '*path', to: 'home#index'

If you wish to provide routing to both POST and GET requests you can still use match, but Rails wants you to specify the request method via via.

  match "*path" => "home#index", via: [:get, :post]  

Remember that routes.rb is executed sequentially (matching the first route that fits the supplied path structure), so put wildcard catching at the bottom of your matchings.
