HTTP status codes look like numbers and behave like signals. Debugging a 401 as if it were a 403 wastes an afternoon, because one means authenticate and the other means you are not allowed regardless.
Search any HTTP status code for its meaning and category. Use it when a client integration misbehaves, and check the code category before you blame the wrong layer of the stack.
