Request and Response
summary
Examines Rails request/response internals and shows a working Ruby HTTP/2 server integrated into Webrick and Rails, using event listeners to convert connections into request/response objects. Demonstrates concrete problems: long Rack middleware stacks, mutable-string allocations, and the brittle array-based response API. Implements server push via view helpers to push assets and reports real-world gains (around 200 ms faster first requests in one slow app).
