Answer 1

for specific session lets say you want to make timeout for this session Session["foo"] =14 min you can do like this

DateTime timenow=DateTime.now;
DateTime timeafter14min=timenow.AddMinuits(14);

if(DateTime.Now>timeafter14min)
{
 HttpContext.Current.Session["foo"]=null;
}

session not expired but cleared
