Re: Adding a cookie via a filterChain...

[Les Parker]

Thanks Craig for your help.

Here is what does'nt seem to work...  Any ideas??  

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;
   }
}
