CloudSeed is a middleware helper for CloudFront custom origins. It tweaks requests to make them work better with CloudFront:
- Adds a Vary header for GZIP compressable content
- Looks for CloudFront compatible version tags on URLs (CloudFront ignores querystrings, this uses URLs like: http://example.com/resource.v1234.gif
If you want to use this for static assets in a Rails 3 app (the /public/ directory), make sure you insert it before ActionDispatch::Static, this line in config/application.rb works:
config.middleware.insert_before ActionDispatch::Static, CloudSeed::Middleware
