title: Updating static assets in public folder with Rails3 on Heroku
body: <p>I have a few files in the public folder of my Rails app that aren't part of the asset pipeline (such as sitemap.xml or a .js file for an embedabble widget).</p>
  
  <p>While I have no issues updating the assets in the public/assets folder, I have troubles updating these static files. Strangely, I can add new files, but I can't update existing ones. When I do update them in development, the modifications aren't taken into account on production environment (Heroku).</p>
  
  <p>I have tried many things but can't seem to find a solution. Any idea ?</p>
