The default behavior is to respect common proxy system properties and environment variables.

JVM System Properties:

• https.proxyHost

• https.proxyPort

• http.nonProxyHosts

• http.noProxyHosts

Environment variables in the given order:

• http_proxy, HTTP_PROXY

Disabling proxy selection explicitly by using ProxySelector.NoProxy

proxySelector = ProxySelector.NoProxy
