Apache HttpClient 4.3 - setting connection idle timeout

Question

What's the shortest way to configure connection idle timeout on Apache HttpClient 4.3 version?

I've looked in the documentation and couldn't find anything. My goal is to reduce open connections to a minimum post server-peak.

for example in Jetty Client 8.x you can set httpClient.setIdleTimeout: http://download.eclipse.org/jetty/stable-8/apidocs/org/eclipse/jetty/client/HttpClient.html#setIdleTimeout(long)

The timeout is set in the RequestConfig so you could set the default when the HttpClientBuilder is called.

For example assuming your timeout variable is in seconds to create your custom RequestConfig you could do something like this:

RequestConfig config = RequestConfig.custom()
    .setSocketTimeout(timeout * 1000)
    .setConnectTimeout(timeout * 1000)
    .build();

You could then build your HttpClient setting the default RequestConfig like this:

HttpClients.custom()
    .setDefaultRequestConfig(config);
