1. What is Middleware?

Junior
  1. A.a terminal delegate that ends the pipeline and never calls the next component
  2. B.a component assembled into the request pipeline that handles a request and optionally forwards it to the next component
  3. C.the method that adds an inline component which can run code before and after invoking the next delegate in the chain
  4. D.the rule that the sequence in which components are registered determines how requests and responses are processed, so misplacement can break behavior
