Session Adding On login Page

Means if you copy paste the url directly in browser would you like to redirect to Default page if so, you can do it by using Session

Sample code in your default2 Page_Load

protected void Page_Load(object sender, EventArgs e)

{

if(Session["User"]==null)
{
Response.Redirect("Default.aspx");
}

}

and your code

protected void Login1_Authenticate(object sender, AuthenticateEventArgs e)

{

bool Authenticated = false;

Authenticated = SiteLevelCustomAuthenticationMethod(Login1.UserName, Login1.Password);

e.Authenticated = Authenticated;

if (Authenticated == true)

{

Session["User"]=Login1.UserName.ToString();

Response.Redirect("Default2.aspx");

}

}

Try this and let me know
