Well-Known URI를 정의하고 싶다면

This article presents practical guidelines from Mark Nottingham, one of the RFC authors, on when to use Well-Known URIs properly and common pitfalls to avoid. Many protocol designers adopt Well-Known URIs for convenience and perceived authority, but this approach rigidifies deployments and creates interoperability problems when the precondition—that clients already know the site—isn't met. Careful consideration of hostname resolution, redirect handling, discovery scope, and migration paths is essential to prevent deployment inflexibility and unexpected operational complexity.
