public class NettyHttpClient<I,O>
extends LoadBalancingRxClientWithPoolOptions<io.reactivex.netty.protocol.http.client.HttpClientRequest<I>,io.reactivex.netty.protocol.http.client.HttpClientResponse<O>,io.reactivex.netty.protocol.http.client.HttpClient<I,O>>
implements io.reactivex.netty.protocol.http.client.HttpClient<I,O>

A Netty HttpClient that can connect to different servers. Internally it caches the RxNetty's HttpClient, with each created with a connection pool governed by CompositePoolLimitDeterminationStrategy that has a global limit and per server limit.

Submit a request to server chosen by the load balancer to execute. An error will be emitted from the returned Observable if there is no server available from load balancer.

Parameters:

errorHandler - A handler to determine the load balancer retry logic. If null, the default one will be used.

requestConfig - An IClientConfig to override the default configuration for the client. Can be null.

Returns:
