Plzzzz Help Me

Thanks

you have two solutions to leverage that
first solution:
you can perform an authentication based on user id and password
go to the config file and add this code

    
        
        
            
                
                    
                
           
If you're  not authenticated no user id and no password corrects then you will be transfered to the page1

solution 2

You can leverage an authentication based on user role, if he/she is admin then he/she enters the protected zone otherwise he/she couldn't as a normal user

in the page 2 and 3 load or init event ad this code

if(page.IsPostBack())
{
    if(HttpContext.Current.User.IsInRole("admin"))
    {
        Server.Transfer( "page.aspx");
    }
}
