* The easiest way to pin a host is turn on pinning with a broken configuration and read the
 * expected configuration when the connection fails. Be sure to do this on a trusted network, and
 * without man-in-the-middle tools like [Charles][charles] or [Fiddler][fiddler].
 *
 * For example, to pin `https://publicobject.com`, start with a broken configuration:
 *
 * ```java
 * String hostname = "publicobject.com";
