HTTP response

As explained in Refactoring to Rust

An HTTP response is a structured message returned by an HTTP server containing the outcome and any result of processing an HTTP request.

How Refactoring to Rust covers it

How deep it goes

Explains headers, pooled allocation, byte copying, pointer boundaries, and output chaining, stopping at implementation-level FFI details.

Examples

Uses a calculator result, NGINX buffers, a full handler, and a curl request producing 10.

What it assumes

Assumes familiarity with Rust strings, unsafe FFI pointers, NGINX request structures, and HTTP request handling.

What you can do after

Build it from scratch as an NGINX Rust handler that returns calculated text with a status code and body.

How it connects

Ties HTTP responses to status codes, headers, Content-Length, memory pools, buffers, output chains, and FFI.
