title: Run rails app under subfolder
body: <p>I've been testing my rails app on localhost:3000 and it works just fine. However, when deploying to my host, the root URL is:</p>
  
  <p><a href="http://99.88.77.66/~username" rel="nofollow">http://99.88.77.66/~username</a></p>
  
  <p>I do not have a domain name at this point.</p>
  
  <p>When I point the browser to the above URL I get the root not found for:</p>
  
  <p>/~username</p>
  
  <p>Alternatively for</p>
  
  <p><a href="http://99.88.77.66/~username/controller/index" rel="nofollow">http://99.88.77.66/~username/controller/index</a></p>
  
  <p>I get this route not found:</p>
  
  <p>/~username/controller/index</p>
  
  <p>I'm using Rials 4.2.3 and Ruby 2.0.</p>
  
  <p>How can I make my routes work with this kind of subfolder until I can get an appropriate domain name?</p>
