title: 301 Redirect using just routes, no controller
body: <p>I'd like to do a 301 redirect, but I want a catch all.  What I currently have is, the domain is hosted on Wordpress and I have both pages and posts. If those pages or posts don't exist on my new rails app, I want to redirect to the home page.</p>
  
  <p>I'm using Heroku to host this, so I can't do it with the web server, as far as I know, so I need to do it inside of Rails. I don't have a controller per se, but I could highjack the page's controller and use that. Is there a way I can put something at the bottom of the routes file that says, "If this page doesn't exist, re-route it to the homepage"?</p>
