+/**
+ * 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.
