Examples of org.apache.http.impl.client.HttpClientBuilder

org.apache.http.impl.client.HttpClientBuilder
Builder for {@link CloseableHttpClient} instances.
When a particular component is not explicitly this class will use its default implementation. System properties will be taken into account when configuring the default implementations when {@link #useSystemProperties()} method is called prior to calling{@link #build()}.
