Request pipeline
A request pipeline is an ordered sequence of processing components through which HTTP requests and their responses pass in a web application.
Pro ASP.NET Core 7, Tenth Edition
A request pipeline is an ordered processing path through which an application passes HTTP requests and responses.
- How it is used
- Organizes how ASP.NET Core processes HTTP requests and returns responses through ordered middleware.
- How deep it goes
- Explains request and response flow, registration order, short-circuiting, branching, and configuration; develops custom middleware through application examples.
- Examples
- Uses ordered Population and Capital middleware, browser-checkable URLs, a database-counting test endpoint, and session configuration.
- What you can do after
- Build it from scratch with Program.cs middleware registrations, then check URL behavior and diagnose ordering or forwarding problems.

Building Web APIs with ASP.NET Core
The HTTP request pipeline is the ordered sequence of ASP.NET Core middleware through which an HTTP request and response are processed.
- How it is used
- Handles HTTP requests by composing reusable middleware in Program.cs.
- How deep it goes
- Explains middleware responsibilities, ordering, short-circuiting, and terminal behavior without descending into implementation internals.
- Examples
- Uses HTTPS redirection, Swagger, authorization, controller mapping, static files, and app.Run() as pipeline examples.
- What you can do after
- Operate/configure it by arranging ASP.NET Core middleware and identifying components that terminate request processing.
