The simplest thing to do is to make sure your routes do not match bad URLs. By default Rails will return a 404 for routes that do not exist.

If you can't do this the default 404 page lives at /404 so you can redirect to that location. Something to keep in mind here, however, is that this type of redirect will perform a 301 Permanent Redirect instead of a 302. This may not be the behavior that you want. To do this you can do the following:

match "/go/(*url)", to: redirect('/404')

Instead, I'd recommend setting up a before filter in your action that instead raises a not found exception. I'm not exactly sure if this exception is in the same place in Rails 4, but with Rails 3.2 I'm currently using:

raise ActionController::RoutingError.new('Not Found')

You can then do any processing and URL checking in the controller (if complicated checking of the URL format is required).
