36   * A SPDY Server that responds to a GET request with a Hello World.
37   * <p>
38   * This class must be run with the JVM parameter: {@code java -Xbootclasspath/p:<path_to_npn_boot_jar> ...}.
39   * The "path_to_npn_boot_jar" is the path on the file system for the NPN Boot Jar file which can be downloaded from
40   * Maven at coordinates org.mortbay.jetty.npn:npn-boot. Different versions applies to different OpenJDK versions.
41   * See <a href="http://www.eclipse.org/jetty/documentation/current/npn-chapter.html">Jetty docs</a> for more
42   * information.
43   * <p>
44   * You may also use the {@code run-example.sh} script to start the server from the command line:
45   * <pre>
46   *     ./run-example.sh spdy-server
47   * </pre>
48   * <p>
49   * Once started, you can test the server with your
50   * <a href="http://en.wikipedia.org/wiki/SPDY#Browser_support_and_usage">SPDY enabled web browser</a> by navigating
51   * to <a href="https://localhost:8443/">https://localhost:8443/</a>
