/**
 * A SPDY Server that responds to a GET request with a Hello World.
 * 
 * This class must be run with the JVM parameter: {@code java -Xbootclasspath/p: ...}.
 * The "path_to_npn_boot_jar" is the path on the file system for the NPN Boot Jar file which can be downloaded from
 * Maven at coordinates org.mortbay.jetty.npn:npn-boot. Different versions applies to different OpenJDK versions.
 * See Jetty docs for more
 * information.
 * 

 * You may also use the {@code run-example.sh} script to start the server from the command line:
 * 
 *     ./run-example.sh spdy-server
 * 
 * 
 * Once started, you can test the server with your
 * SPDY enabled web browser by navigating
 * to https://localhost:8443/
