使用会话.并检查会话变量，如果用户已经登录，则不显示登录页面或将其重定向到其他页面，例如主页等.

Use Session. And check the session variable, and if the user has already logged in, don''t show the login page or redirect him to another page for e.g. Home page etc.

<script language=javascript>
            function fnBack()
            {
                history.go(-1)
            }
        </script>
