Is there a simple way to accept both success (2xx) and redirects (3xx) in HttpClient, but throw on 4xx and 5xx?
expectSuccess throws on redirects (3xx) as well.

You can add your custom response validator. Here is an example:

val client = HttpClient(CIO) {
    HttpResponseValidator {
        validateResponse { response ->
            if (response.status.value >= 400) {
                throw RuntimeException("Invalid response with status ${response.status}")
            }
        }
    }

}

client.get("<http://httpbin.org/status/404>")
