Quick Answer
The request pipeline is a chain of middleware components. Each middleware can inspect and modify the request, call the next middleware, and modify the response on the way back. Order matters - defined in Program.cs. For Web API: UseRouting -> UseAuthentication -> UseAuthorization -> MapControllers. Request flows forward through middleware, response flows backward.
Answer
The pipeline consists of middleware components that process HTTP requests in sequence:
Request enters server
Middleware handles tasks like authentication, logging, routing
Endpoint routing selects controller/action
Controller executes business logic
Response flows back through middleware
