Rick Bryant sent me some sample code he wrote which shows how to use the RESTful Cache Server from Java. Thanks Rick. To use the sample just fire up the cache server: startup.sh and then run the following Java code.
package samples;
import java.io.InputStream;
import java.io.OutputStream;
import java.net.HttpURLConnection;
import java.net.URL;
