Request and Response

" summary

Explains exactly how Rails handles an HTTP request: the Rack call stack, why the router is buried, and why the ENV hash and array response shape force extra allocations and make streaming awkward. Demonstrates a Webrick + H2 integration that returns a simple "Hi Mom" response, proposes migrate ENV hash to Request/Response objects, measures reduced allocations from three to zero for one middleware rewrite, and outlines using HTTP/2 server push via Nginx link headers to speed development.
