What's the difference between 301 and 302?
301 Moved Permanently tells clients the resource has permanently moved · search engines transfer ranking. 302 Found is a temporary redirect · the original URL keeps its ranking.
When should I use 401 vs 403?
401 Unauthorized means "not authenticated" · the client should provide credentials. 403 Forbidden means "authenticated but not allowed" · credentials won't help.
What does a 418 status code mean?
418 "I'm a teapot" is an April Fools' joke from RFC 2324 (Hyper Text Coffee Pot Control Protocol). It's not used in practice but is widely known in developer culture.
