HttpAsyncClientBuilder (Apache HttpClient 5.4.1 API)

java.lang.Object
- org.apache.hc.client5.http.impl.async.HttpAsyncClientBuilder

```
public class HttpAsyncClientBuilder
extends Object
```
Builder for CloseableHttpAsyncClient instances that can negotiate the most optimal HTTP protocol version during the TLS handshake with ALPN extension if supported by the Java runtime.
Concurrent message exchanges executed by CloseableHttpAsyncClient instances created with this builder will get automatically assigned to separate connections leased from the connection pool.

When a particular component is not explicitly set this class will use its default implementation. System properties will be taken into account when configuring the default implementations when useSystemProperties() method is called prior to calling build().
- http.proxyHost
- http.proxyPort
- https.proxyHost
- https.proxyPort
- http.nonProxyHosts
- http.keepAlive
- http.agent
Please note that some settings used by this class can be mutually exclusive and may not apply when building CloseableHttpAsyncClient instances.
