title: Rails relative_url doesnt adjust links
body: <p>After failed attempts with Passenger (see my other question), I managed to get rails running via a reverse proxy in a subfolder.
  I added the lines</p>
  
  <pre><code>config.relative_url_root = "/App"
  config.action_controller.relative_url_root = "/App"
  </code></pre>
  
  <p>to my environment. Now I can access my rails project under www.mySite.com/App. The problem is that the links /paths dont add the prefix "/App". So a link to "users" looks like
  <code>www.mySite.com/users</code> instead of <code>www.mySite.com/App/users</code>.
  How can I change this?</p>
  
  <p>At least according to <a href="http://edgeguides.rubyonrails.org/configuring.html#deploy-to-a-subdirectory-relative-url-root" rel="noreferrer">http://edgeguides.rubyonrails.org/configuring.html#deploy-to-a-subdirectory-relative-url-root</a> I did everything correct.</p>
