Thanks for your help...   public final class SessionControlFilter implements Filter {    private String attribute = null;    private FilterConfig filterConfig = null;    public void init(FilterConfig filterConfig) throws ServletException    {       this.filterConfig = filterConfig;       this.attribute = filterConfig.getInitParameter("attribute");       sessionController = SessionController.getInstance();    }    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)       throws IOException, ServletException    {       if (attribute != null) request.setAttribute(attribute, this);       if(getCookie((HttpServletRequest)request, "CHOCLATE_CHIP") == null)       {         makeCookie((HttpServletResponse)response, "CHOCLATE_CHIP", "CLIENT", "666");        }       chain.doFilter(request, response);    }    public static Cookie getCookie(HttpServletRequest request, String name)    {       Cookie[] cookies = request.getCookies();       Cookie myCookie = null;       for (int i=0;i<cookies.length ;i++ )       {          if (cookies[i].getName().equals(name))          {             myCookie = cookies[i];             break;          }       }       return myCookie;    }    public void makeCookie(HttpServletResponse response, String name, String channel, String visitorId)       {       String value = channel + "|" + visitorId;       Cookie newCookie = new Cookie(name, value);       newCookie.setPath("/");       newCookie.setComment("No comment.");       newCookie.setMaxAge(315360000);       newCookie.setVersion(1);       response.addCookie(newCookie);    }    public void destroy()    {        this.attribute = null;        this.filterConfig = null;    } }     This electronic mail transmission may contain confidential information and is intended only for the person(s) named.
