022/**
023 * Exception representing an HTTP 401 (Unauthorized).
024 *
025 * <p>
026 * Similar to <c>403 Forbidden</c>, but specifically for use when authentication is required and has failed or has not yet been provided.
027 * <br>The response must include a WWW-Authenticate header field containing a challenge applicable to the requested resource.
028 * <br>401 semantically means "unauthenticated",i.e. the user does not have the necessary credentials.
029 * <br>Note: Some sites issue HTTP 401 when an IP address is banned from the website (usually the website domain) and that specific address is refused permission to access a website.
030 *
031 * @deprecated Use {@link org.apache.juneau.http.exception.Unauthorized}
