Hi Trevor, Keenan is right in that Heroku doesn't support the X-sendfile method:
- http://devcenter.heroku.com/articles/rack-sendfile The support team initially added this documentation last year after I submitted an issue regarding problems I was having serving Sass- generated files from `./tmp` using Rack::Static. The relevant part of my Rails configuration looked like this: Sass::Plugin.options[:template_location] = { "#{Rails.root}/app/stylesheets" => "#{Rails.root}/tmp/stylesheets" } Rails.configuration.middleware.insert_after 'Sass::Plugin::Rack', 'Rack::Static', :urls => ['/stylesheets'], :root => "#{Rails.root}/tmp" This worked in a simple Rack app, but not in Rails--I kept getting a 503 error. A member of the Heroku support team suggested that I remove Rack::Sendfile from my middleware stack, and that solved the issue. Since Rack::Static delegates to Rack::File, Rack::Sendfile will add the `X-Sendfile` header. And since Heroku doesn't support the use of Rack::Sendfile, file downloads will fail. When I first found about this, I just removed Rack::Sendfile from my middleware stack, but it seems Heroku is now getting round this automatically by configuring Rails to disable the `X-Sendfile` header. -- You received this message because you are subscribed to the Google Groups "Heroku" group.
