HTTP response
An HTTP response is a protocol message sent by a server to a client after an HTTP request, containing status information, headers, and optionally a body.
Rust Servers, Services, and Apps
HttpResponse is a Rust structure representing an HTTP response message with status information, headers, and an optional body.
- How it is used
- Carries handler-produced status, headers, and body through a custom server’s HTTP serialization and client response flow.
- How deep it goes
- Defines fields, defaults, constructor, string conversion, stream writing, and tests; also exposes a body-unwrapping limitation in the serializer.
- Examples
- Tests 200 and 404 construction and a serialized 404 message, then returns HTML pages and JSON data from handlers.
- What you can do after
- Build it from scratch as a Rust response type that handlers construct and serialize for HTTP clients.

ASP.NET Core in Action, 3e
HttpResponse is the ASP.NET Core object representing the HTTP response sent to a client, including its status code, headers, content type, and body.
- How it is used
- Customizes minimal API responses when ordinary return conventions or Results helpers do not meet endpoint requirements.
- How deep it goes
- Explains handler injection and manually sets status code, content type, and body, while deferring broader response features to helpers.
- Examples
- Demonstrates a /teapot endpoint returning status 418, text/plain content, and an I'm a teapot body.
- What you can do after
- Build it from scratch by injecting HttpResponse and writing a customized minimal API response.

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 it is used
- Connects a Rust-calculated result to NGINX’s HTTP output pipeline.
- 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 you can do after
- Build it from scratch as an NGINX Rust handler that returns calculated text with a status code and body.
Pro ASP.NET Core 7, Tenth Edition
An HTTP response is a server message returned in response to an HTTP request, containing status information and optionally response content.
- How it is used
- Uses HTTP responses to return status information and content from middleware, endpoints, and web services.
- How deep it goes
- Explains response properties and pipeline timing, then demonstrates conditional body writing without descending into transport internals.
- Examples
- Demonstrates a GET request with a custom query value that returns plain text through middleware.
- What you can do after
- Operate/configure middleware responses by setting metadata, writing body content, redirecting clients, and respecting response-start timing.
