Introducción

Rack::Response provides a convenient interface to create a Rack response.

It allows setting of headers and cookies, and provides useful defaults (a OK response containing HTML).

You can use Response#write to iteratively generate your response, but note that this is buffered by Rack::Response until you call finish.

Alternatively, the method finish can take a block inside which calls to write are synchronous with the Rack response.

Your application‘s call should end returning Response#finish.
