title: Rails app in a subdirectory
body: <p>Trying to set up a Rails app in a subdirectory. My server is Cherokee. I have a base url of: 
  www.nonsense.com, which is a wordpress blog, and I wish to set up a rails app in, www.nonsense.com/rails_app.</p>
  
  <p>A quick scan of google led me to using: ActionController::AbstractRequest.relative_url_root = "/rails_app"</p>
  
  <p>However, it seems this has been removed in the latest Rails. Any ideas as to the equivalent in Rails 2.3.8?</p>
