 *  Fix: Follow HTTP 307 and 308 redirects on methods other than GET and POST. We're reluctant to
    change OkHttp's behavior in handling common HTTP status codes, but this fix is overdue! The new
    behavior is now consistent with [RFC 7231][rfc_7231_647], which is newer than OkHttp itself.
    If you want this update with the old behavior use [this interceptor][legacy_interceptor].

Und normalerweise ist es ein komplexes und „schwieriges“ Thema.

In vielen Frameworks und Systemen erfordert allein die Handhabung von Sicherheit und Authentifizierung viel Aufwand und Code (in vielen Fällen kann er 50 % oder mehr des gesamten geschriebenen Codes ausmachen).

		return fmt.Errorf("%s returned '%s', please check if your auth token is correctly set", target.args.Endpoint, resp.Status)
