/**
 * Interface for checking if a hostname matches the names stored inside the
 * server's X.509 certificate.  Implements javax.net.ssl.HostnameVerifier, but
 * we don't actually use that interface.  Instead we added some methods that
 * take String parameters (instead of javax.net.ssl.HostnameVerifier's
 * SSLSession).  JUnit is a lot easier this way!  :-)
 * <p/>
 * We provide the HostnameVerifier.DEFAULT, HostnameVerifier.STRICT, and
 * HostnameVerifier.ALLOW_ALL implementations.  But feel free to define
 * your own implementation!
 * <p/>
 * Inspired by Sebastian Hauer's original StrictSSLProtocolSocketFactory in the
 * HttpClient "contrib" repository.
