After "n" test sessions, the proxy disconnects from the grid and issues a requests to64 * {@link NodeForceRestartServlet}. The number of unique sessions is controlled via the json config file65 * <code>SeLionConfig.json</code> with the setting <code>uniqueSessionCount</code>.<br>66 * <br>67 * For example:68 *69 * <pre>70 *  "uniqueSessionCount": 2571 * </pre>72 *73 * Here the value 25 indicates that the proxy will stop accepting new connections after 25 unique sessions and trigger a74 * graceful shutdown (see below). A value of <=0 indicates that this feature is disabled.</li>75 *76 * <li>Request remote proxy to shutdown either forcefully or gracefully -- issues a request to77 * {@link NodeForceRestartServlet}. In the case of a graceful restart, the proxy respects a wait timeout for any78 * sessions in progress to complete. This is controlled via the json config file <code>SeLionConfig.json</code> with the79 * setting <code>nodeRecycleThreadWaitTimeout</code>.<br>80 * <br>81 * For example:82 *83 * <pre>84 *  "nodeRecycleThreadWaitTimeout": 30085 * </pre>86 *87 * Here the value 300 is in seconds -- the proxy will wait this amount of time before forcing a shutdown action. A value88 * of 0 indicates that the proxy will wait indefinitely.</li>89 *90 * <li>Request remote proxy to auto upgrade -- issues a request to {@link NodeAutoUpgradeServlet}.</li>91 *92 * <li>Determine whether the remote proxy supports {@link NodeAutoUpgradeServlet}, {@link NodeForceRestartServlet}, and93 * {@link LogServlet}</li>94 * </ul>95 */96public class SeLionRemoteProxy extends DefaultRemoteProxy {97    private static final SeLionGridLogger LOGGER = SeLionGridLogger.getLogger(SeLionRemoteProxy.class);98    private static final int DEFAULT_MAX_SESSIONS_ALLOWED = 50;99    private static final int CONNECTION_TIMEOUT = 30000;100    private volatile boolean scheduledShutdown;101    private volatile int totalSessionsCompleted, totalSessionsStarted;102    private final boolean canForceShutdown, canAutoUpgrade, canViewLogs;103    private final long proxyStartMillis;104    private final SimpleLogger proxyLogger;105    private final String machine;106    private final NodeRecycleThread nodeRecycleThread;107    private final Lock accessLock;108    /**109     * @param request110     *            a {@link RegistrationRequest} request which represents the basic information that is to be consumed by111     *            the grid when it is registering a new node.112     * @param registry113     *            a {@link GridRegistry} object that represents the Grid's registry.114     * @throws IOException115     */116    public SeLionRemoteProxy(RegistrationRequest request, GridRegistry registry) throws IOException {117        super(request, registry);118        proxyStartMillis = System.currentTimeMillis();119        scheduledShutdown = false;120        totalSessionsCompleted = 0;121        totalSessionsStarted = 0;122        machine = getRemoteHost().getHost();123        nodeRecycleThread = new NodeRecycleThread(getId());124        accessLock = new ReentrantLock();125        // Setup the proxy logger126        SimpleLoggerSettings loggerSettings = new SimpleLoggerSettings();127        loggerSettings.setUserLogFileName(machine + ".log");128        loggerSettings.setLogsDir(SeLionGridConstants.LOGS_DIR);129        loggerSettings.setDevLevel(Level.OFF);130        loggerSettings.setLoggerName(machine);131        loggerSettings.setClassName(SeLionRemoteProxy.class.getSimpleName());132        loggerSettings.setIdentifier("SeLion-Grid-" + SeLionBuildInfo.getBuildValue(SeLionBuildProperty.SELION_VERSION));133        loggerSettings.setMaxFileCount(1);134        loggerSettings.setMaxFileSize(5);135        proxyLogger = SimpleLogger.getLogger(loggerSettings);136        // Log initialization info137        final int port = getRemoteHost().getPort();138        StringBuffer info = new StringBuffer();139        info.append("New proxy instantiated for the node ").append(machine).append(":").append(port);140        proxyLogger.info(info.toString());141        info = new StringBuffer();142        if (isEnabledMaxUniqueSessions()) {143            info.append("SeLionRemoteProxy will attempt to recycle the node ");144            info.append(machine).append(":").append(port).append(" after ").append(getMaxSessionsAllowed())145                .append(" unique sessions");146        } else {147            info.append("SeLionRemoteProxy will not attempt to recycle the node ");148            info.append(machine).append(":").append(port).append(" based on unique session counting.");149        }150        proxyLogger.info(info.toString());151        // Enable the cache to store the browser information only when the152        // "com.paypal.selion.grid.servlets.GridStatistics" is enabled - results in153        // better memory management if the servlet is not loaded154        if (isSupportedOnHub(GridStatistics.class)) {155            updateBrowserCache(request);156        }157        // detect presence of SeLion servlet capabilities on proxy158        canForceShutdown = isSupportedOnNode(NodeForceRestartServlet.class);159        canAutoUpgrade = isSupportedOnNode(NodeAutoUpgradeServlet.class);160        canViewLogs = isSupportedOnNode(LogServlet.class);161    }162    /**163     * Determine if the hub supports the servlet in question by looking at the registry configuration.164     * @param servlet165     *            the {@link HttpServlet} to ping166     * @return <code>true</code> or <code>false</code>167     */168    private boolean isSupportedOnHub(Class<? extends HttpServlet> servlet) {169        LOGGER.entering();170        final boolean response = getRegistry().getHub().getConfiguration().servlets.contains(servlet.getCanonicalName());171        LOGGER.exiting(response);172        return response;173    }174    /**175     * Determine if the remote proxy supports the servlet in question by sending a http request to the remote.
