Hello!
I want to keep some different data in one cookie file and write this class, and want to know - is this good? For example - user JS enable.When user open his first page on my site, i write to session his GMT time and write with this manager JS state. (GMT time is ajax request with js). And i want to keep some data in this cookie (up to 10 values). Have any advices or tips?

string[] dels = data.Split(DelimeterValue, StringSplitOptions.RemoveEmptyEntries);
foreach (string delValue in dels)
{
int eqIndex = delValue.IndexOf("=");
if (eqIndex == -1)
continue;
int cookieType = ValidationHelper.GetInteger(delValue.Substring(0, eqIndex), 0);
if (!Enum.IsDefined(typeof(CookieSetting), cookieType))
continue;
CookieSettingValue value = new CookieSettingValue();
value.Type = (CookieSetting)cookieType;
value.Value = delValue.Substring(eqIndex + 1, delValue.Length - eqIndex-1);
_data.Add(value);
}
return _data;

inList.Type = type;
inList.Value = value.ToString();
_data.Add(inList);
}
else
{
inList.Value = value.ToString();
}
}

private string ToCookie()
{
StringBuilder sb = new StringBuilder();
for (int i = 0; i < _data.Count; i++)
{
sb.Append((int)_data[i].Type);
sb.Append("=");
sb.Append(_data[i].Value);
sb.Append(DelimeterValue[0]);
}
return sb.ToString();

P.S. i want to keep many data in one cookies file to compress data and decrease cookies count.
