title: Is everyone allowed to access rails public folder via URL?
body: <p>When assets like images or files are in the rails public directory with asset pipeline enabled, is everyone allowed to access them through URL?</p>
  
  <p>I am asking this because now I am learning about implementing File Uploading through Carrierwave with the help of the book, Rails 4 in Action, and it says the files should be moved outside the public folder for access control. </p>
  
  <p>If assets are in the public folder, does it mean that we can't do access control?</p>
