Anonymous Users Not Working on Load of page From login page

 In a button click i  transfer the user to form1 where  HttpContext.Current.User.Identity.Name.ToString does not have a value on this page until a postback occurs, how do i simulate a postback in code behind?

Hi,
Are you using  Server.Transfer("url");? Method Transfer() will not bring user's credential while redirect page(do not have cookie). 
Instead,you can use Response.Redirect("url");
