Answer 1

thank you very much for your support! Your post get me going on. After some cups of coffee i found a working solution. Actually i am doing the following, which works for me:

def download_file
  filename = params[:file]
  raw = StringIO.new('')
  @ftp.retrbinary('RETR ' + filename, 4096) { |data|
    raw << data
  }
  @ftp.close
  raw.rewind
  send_data raw.read, :filename => filename
end

I will test this in production(real life situation). If this is not working well enough, i have to use a NFS mount.
