Even ignoring other frameworks, Rails has supported streaming through various APIs since at least the 2.x days.

In Rails 2, you would pass a Proc to the render method giving direct access to the response.

Rails 3 changed the API to any Enumerable assigned to self.response_body, as described in the article.

Rails 4 gets yet another API. It may be arguably cleaner, but the end functionality remains the same as it has always been.
