import dointerface.ApplicationSource;

public class OnlineFilter extends HttpServlet implements Filter
{
 private static final long serialVersionUID = 1L;
 public void init(FilterConfig filterConfig) throws ServletException
 {
  
 }
 public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException 
 {
  HttpServletRequest httpRequest = (HttpServletRequest)request;
