Sessions we can be used to store data for the user specific like cookies.
sessions will use cookies to store the data.
Sessions we can used easily in ASP.NET with the Session object. We will re-use the cookie example,
and use sessions instead. sessions will expire after a certain amount of minutes,as configured in the web.config file.
