AsyncClientImpl

Create a new client sharing the same underlying http client

Send an HTTP request and get the response in Scala Future type.

It will return Future[HttpClientException] for non-successful responses. For example, when receiving non-retryable status code (e.g., 4xx), it will return Future[HttpClientException]. For server side failures (5xx responses), this continues request retry until the max retry count.

If it exceeds the number of max retry attempts, it will return Future[HttpClientMaxRetryException].

Send an HTTP request and returns a response (or the last response if the request is retried)
