Subject: x_sendfile_header now defaults to nil and production.rb env file
 doesn't set a particular value for it. This allows servers to set it through
 X-Sendfile-Type, read
 https://github.com/rack/rack/blob/master/lib/rack/sendfile.rb for more info.
 Anyways you can force this value in your production.rb
