这是首页的代码，输入用户名和密码登录登录成功后显示用户的登录信息，在点击退出按钮后页面跳转到login.aspx同时清除了session,但是在login.aspx页单击鼠标右键后退还能退回到登录成功的首页，怎么才能把session全部处理掉呢？请高手指教！着急！！

Session.RemoveAll();

嘿嘿 刚好碰到我也需要解决这个问题 楼上的回答试了可以用 顶下

Sub close(ByVal sender As Object, ByVal e As System.EventArgs) 退出按钮事件
Session.Clear()
Session.RemoveAll()
Session.Abandon()
Response.Redirect("login.aspx")
End Sub
兄弟我在这已经用了，可是后退以后还能到登录好的那个状态！

再顶一下，这个问题还是没有解决！
