如何限制用户输入直接网址 [英] How to restrict user to enter direct url

问题描述

大家好

我想限制用户输入直接网址.

如果用户尝试输入url，则应重定向回用户访问的最后一页.


我使用了Request.ServerVariables ["HTTP_REFERER"].当用户输入直接URL时，它将返回"Null".

这样我就可以得到用户输入的直接网址

但是如何将用户重定向到他/她访问的最后一页?

有没有其他更好的替代方法可以实现呢?

请指教.

谢谢

Hi all

I want to restrict user to enter direct url.

If user tries to enter url then it should redirect back to the last page that the user visited.


I used Request.ServerVariables["HTTP_REFERER"] . When user enters direct url then it returns "Null".

So I can get , user entered direct url

But how to redirect the user to the last page he/she visited ?

Is there any preferable alternative way to implement this ?

Please advise.

Thanks
