Kimec :
I am using reactor-netty http client (0.7.X series) with connection pooling and would like to configure pooled connection's idle timeout but don't know where.
More precisely, I need to configure reactor-netty http client connection pool in such a way that it will automatically close connections that did not see any activity within configurable timeout. These connections are open but no bytes were transferred in or out for some (configurable) amount of time.
How can I configure reactory-netty http client to close idle connections preemptively?

I was able to accomplish this on the 0.7.x branch by adding netty write and read time-out handlers to the channel pipeline. However, on 0.8.x, this approach no longer works.
HttpClient httpClient = HttpClient
.create((HttpClientOptions.Builder builder) -> builder
.host(endpointUrl.getHost())
.port(endpointUrl.getPort())
.poolResources(PoolResources.fixed(connectionPoolName, maxConnections, timeoutPool))
.afterChannelInit(channel -> {
channel.pipeline()
// The write and read timeouts are serving as generic socket idle state handlers.
.addFirst("write_timeout", new WriteTimeoutHandler(timeoutIdle, TimeUnit.MILLISECONDS))
.addFirst("read_timeout", new ReadTimeoutHandler(timeoutIdle, TimeUnit.MILLISECONDS));
})
.build());
