Presentation: Rack in Rails 3 Presentation [PDF]

One of the largest general architectural enhancements in Rails 3 is a steep increase in modularity. Nowhere is this more evident than the refactoring of ActionController into a series of Rack middleware components. In this talk, we’ll take a look at Rack: why it was created, how it caught fire across Ruby web frameworks, and how to build Rack components that further extend Rails 3’s HTTP pipeline.
