推荐答案

你'在浏览器缓存中检索页面时会看到这一点，因此您的代码（包括身份验证检查）未运行。您可以通过在希望用户进行身份验证的页面上禁用缓存来停止此操作（谷歌如何在aspx页面上禁用缓存），但这会对您网站的性能产生负面影响并增加资源使用量，因此这取决于您决定它是否值得。毕竟当这个人回去时，他们只是看到他们已经看过的东西，所以谁在乎呢？



你不能阻止人们使用back \但是，这是一个错误的树木。

You're seeing this as the pages are being retrieved from the browser cache so your code (including authentication checks) isn't running. You can stop this by disabling caching on pages you want the user to be authenticated to access (google for how to disable caching on an aspx page), but it will adversely affect the performance of your site and increase resource usage so it's up to you to decide if it is worth it. After all when the person goes back\forward they are simply seeing things they have already seen, so who cares?

You can't stop people using back\forward though, it's the wrong tree to be barking up.
