Das ist vergleichbar mit den HTTP-Statuscodes im Bereich 200 (von 200 bis 299). Diese „200“er Statuscodes bedeuten, dass der Request in einem bestimmten Aspekt ein „Success“ („Erfolg“) war.

Die Statuscodes im 400er-Bereich bedeuten hingegen, dass es einen Fehler gab.

Erinnern Sie sich an all diese **404 Not Found** Fehler (und Witze)?
