Class BootstrapProvider

java.lang.Object

software.amazon.awssdk.http.nio.netty.internal.BootstrapProvider

public class BootstrapProvider
extends Object

The primary purpose of this Bootstrap provider is to ensure that all Bootstraps created by it are 'unresolved' InetSocketAddress. This is to prevent Netty from caching the resolved address of a host and then re-using it in subsequent connection attempts, and instead deferring to the JVM to handle address resolution and caching.
