title: rails subdomain
body: <p>I went to this tutorial <a href="http://railscasts.com/episodes/221-subdomains-in-rails-3?autoplay=true" rel="nofollow">http://railscasts.com/episodes/221-subdomains-in-rails-3</a> and trying to implement in <a href="http://ngtv2.info" rel="nofollow">http://ngtv2.info</a> </p>
  
  <p>but after I place the code in routes.rb </p>
  
  <p><i>match '/' => 'projects#show', :constraints => { :subdomain => /.+/ }</i></p>
  
  <p>and then typed <a href="http://kingpangilinan.ngtv2.info" rel="nofollow">kingpangilinan.ngtv2.info</a> </p>
  
  <p>the browser says that "Server not found", <i>Firefox can't find the server at kingpangilinan.ngtv2.info</i></p>
  
  <p>Any help is appreciated.</p>
