Make the browser download the file instead of opening it.

Question

I would like to download http://foobar.com/song.mp3 as song.mp3, instead of having Chrome open it in his native <audio>player in a browser.

How can i do this?

Answer 1

You just need to send these headers:

Content-Disposition: attachment; filename=song.mp3;
Content-Type: application/octet-stream
Content-Transfer-Encoding: binary

The method send_filedoes this for you:

get '/:file' do |file|
  file = File.join('/some/path', file)
  send_file(file, :disposition => 'attachment', :filename => File.basename(file))
end
