/**
* 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.
