We're hosting a Rails app on Heroku, and having some trouble serving some static assets out of the public folder. (I know, this isn't recommended. We actually use CloudFront with a custom origin of our main application so we're getting the benefit of a CDN still. But that's irrelevant for this issue.)
Some assets serve up fine and exactly as expected. Ex: /404.html, /favicon.png
Others return an HTTP 406 error: /video-js/swf/video-js-4.1.0.swf
Rails 4.1.1
Ruby 2.1.2
The rails_12factor gem is present.
production.rb file sets config.serve_static_assets = true
The file definitely exists.. Using the console on Heroku:
File.size("/app/public/video-js/swf/video-js-4.1.0.swf")
=> 14059
But when I try to access the file, I get an HTTP 406 Not Acceptable response
curl -I http://my-rails-application.com/video-js/swf/video-js-4.1.0.swf
returns:
HTTP/1.1 406 Not Acceptable
Content-length: 0
Content-Type: text/html; charset=utf-8

I tried adding a Mime Type for swf files (Mime::Type.register "application/x-shockwave-flash", :swf) and now I get a 404 instead of a 406, but that's still not very useful.
To recap, html, png, jpg, ico, and txt files all are served perfectly. swf, ttf, woff and a few others aren't being served out of the public folder.
What could cause some file types in the public folder to work properly, but not others?
