Rails3: Empty (0 byte) downloads using send_data/send_file
Dienstag, 12. Juli 2011, 09:12 Uhr | roberto@vasquez-angel.de |If you get empty downloads served from a rails application on passenger, the culprit might be following line in your Rails.root/environments/production.rb:
config.action_dispatch.x_sendfile_header = "X-Sendfile"
Remove it, and it should work.
