  • 100’s = for information only, like if the server can’t accommodate what the client is asking.
  • 200’s = success codes, tells the client the request was accepted.
  • 300’s = these tell the client that the information they want is no longer available there, and redirects them.
  • 400’s = error codes.
  • 500’s = error codes, but for the server.
