Google "asp.net identity" or "asp.net membership" (Identity is more up-to-date than Membership). They are use authentication frameworks that have everything you need to manage users and allow them to login.

Hi
while the user is clicking button buy product or add to cart button u should check whether the current user session expired or not.

for that first store user id in a session variable then check whether session["userid"]==null .if it is null redirect to login page

bro i mean.. if not logged in.. like if a person just visits website then he click on add to cart or buy now button.. then message or redirect will be happen.. same like on this website. if we submit a question without sign-in... this message shows "Please log in (or quickly sign up) to post."

Hi
That is wat i told :) .You can handle this thing globally

try this code in your global.asax session_start event
if (HttpContext.Current.Request.IsAuthenticated)
{
FormsAuthentication.SignOut();
Response.Redirect(FormsAuthentication.LoginUrl + "?ReturnUrl=" + Server.UrlEncode(Request.Url.ToString()));

}
then in your login pages's page load event try this code

if (!IsPostBack)
{

if (Request.QueryString["ReturnUrl"] != null && Session["userId"] == null)
{

lblUserLoginError.Text = "Session Expired ! Please Login again";
string script = "function f(){ HideErrorLogin(); Sys.Application.remove_load(f);}Sys.Application.add_load(f);";
ScriptManager.RegisterStartupScript(Page, Page.GetType(), "key", script, true);

}
else if (HttpContext.Current.Request.IsAuthenticated && Session["userId"] != null)
{
Response.Redirect("~/AuthenticatedUser/123.aspx", false);
}
}

Note HideErrorLogin() is a javascript function to show and hide the session expiry message
