Explain Middleware and the Request Pipeline.

Expert .NET Core
Quick Answer The request pipeline is a chain of delegates (middleware). Each middleware can inspect and modify the HttpContext, call next() to continue, or short-circuit. Order is defined in Program.cs. The pipeline processes requests forward and responses backward รขโ‚ฌโ€ response-writing middleware sees the response after all downstream middleware have run.

Answer

Middleware executes sequentially and may process, modify, short-circuit, or delegate requests. Enables flexible, modular pipelines replacing old HttpModules/Handlers.
