title: How can I redirect a 404 Error in a custom 404 page using Codeigniter?
body: <p>Kind sirs,
  I'm using Codeigniter to build a blog. I might need a way to redirect a 404 error into a custom 404 page. Just like what Abduzeedo.com's 404 page. Is it possible to control this by using routes? Or should i use controllers to direct it to another view? Thanks very much!</p>
