/**
* 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/
