/**
 * This class is used to configure the https parameters for each incoming
 * https connection on a HttpsServer. Applications need to override
 * the {@link #configure(HttpsParameters)} method in order to change
 * the default configuration.
 * 
 * The following example shows how this may be done:
 * 

 * 

 * SSLContext sslContext = SSLContext.getInstance (....);
 * HttpsServer server = HttpsServer.create();
 *
 * server.setHttpsConfigurator (new HttpsConfigurator(sslContext) {
 *     public void configure (HttpsParameters params) {
 *
 *         // get the remote address if needed
 *         InetSocketAddress remote = params.getClientAddress();
 *
 *         SSLContext c = getSSLContext();
 *
 *         // get the default parameters
 *         SSLParameters sslparams = c.getDefaultSSLParameters();
 *         if (remote.equals (...) ) {
 *             // modify the default set for client x
 *         }
 *
 *         params.setSSLParameters(sslparams);
 *     }
 * });
 * 
 * @since 1.6
