      Hi there,

      I was wondering what you wanted to know of cookies. The below code demonstrates how to save and retrieve values from cookies.

      function getCookieVal (offset) {
      var endstr = document.cookie.indexOf (";", offset);
      if (endstr == -1)
      endstr = document.cookie.length;
      return unescape(document.cookie.substring(offset, endstr));
      }

      function GetCookie (name) {
      var arg = name + "=";
      var alen = arg.length;
      var clen = document.cookie.length;
      var i = 0;
      while (i < clen) {
      var j = i + alen;
      if (document.cookie.substring(i, j) == arg)
      return getCookieVal (j);
      i = document.cookie.indexOf(" ", i) + 1;
      if (i == 0) break;
      }
      return null;
      }

      function SetCookie (name, value) {
      var argv = SetCookie.arguments;
      var argc = SetCookie.arguments.length;
      var expires = (argc > 2) ? argv[2] : null;
      var path = (argc > 3) ? argv[3] : null;
      var domain = (argc > 4) ? argv[4] : null;
      var secure = (argc > 5) ? argv[5] : false;
      document.cookie = name + "=" + escape (value) +
      ((expires == null) ? "" : ("; expires=" + expires.toGMTString())) +
      ((path == null) ? "" : ("; path=" + path)) +
      ((domain == null) ? "" : ("; domain=" + domain)) +
      ((secure == true) ? "; secure" : "");
      }

      function DeleteCookie (name) {
      var exp = new Date();
      exp.setTime (exp.getTime() - 1);
      var cval = GetCookie (name);
      document.cookie = name + "=" + cval + "; expires=" + exp.toGMTString();
      }
