推荐答案

请参见以下链接


注销后处理浏览器后退按钮

See below link


Handling browser back button after logout

后退按钮将始终将您重定向到先前访问的页面，但是一旦会话被放弃，从该页面进行的进一步前向重定向将受到限制.

或者，您可以使用JavaScript删除以前的历史记录，以使其不再返回并被禁用.

The back button will always redirect you to previously visited page, But further forward redirection from that page will be restricted once session is abandoned.

Alternatively you can use JavaScript to remove previous history so that it will not go back and it will be disabled.

我在注销时也有类似的经历，但实际上并没有.问题不在于尚未正确设置的会话变量，而在于程序逻辑错误.编写这样的程序非常容易:

如果session("seeUserLoginOK")<>然后确定"
错误消息...
如果
结束
....所有其他codse都包含html display

在每个程序中都必须执行的正确方法是:

如果session("seeUserLoginOk")<>然后确定"
错误消息....
其他

....所有其他代码都包括html display

如果
结束
这是一个简单的错误，有经验的传统C程序员很容易陷入.同样也可以阻止不必要的访问.

I have similar experience on the logout and yet not really out. The issue is not on session variable that has not set correctly but on the program logic error. It is very easy to write program like:

if session("seeUserLoginOK") <> "OK" then
error messaging...
end if

.... all other codse include html display

The correct way, and have to be do it in every program, is:

if session("seeUserLoginOk") <> "OK" then
error messaging....
else

.... all other codes include html display

end if

This is a simple error experienced traditional C programmer can easily fell into. It is also impoprtant in stop unwanted access as well.
