浏览器后退按钮显示缓存中的页面? [英] Browser back button showing the page from cache?

问题描述

当我从 wordpress 网站注销时，它会被重定向到登录页面.但问题是，如果我点击浏览器的后退按钮，它会显示需要授权的上一页.我知道，页面是从浏览器缓存加载的，并且没有与服务器进行交互.但如果用户点击浏览器后退按钮，我需要强制页面重新加载.

When I logout from wordpress website, it will be redirected to the login page. But the issue is, if I hit the browser back button, It will show the previous page, which need the authorization. I know, the page is being loaded from the browser cache and no interaction with the server is happening. But I need to force the page to reload if the user hit the browser back button.

我确实检查了标题，我可以找到以下内容

I did check the header and I could find the following

Cache-Control:  no-cache, must-revalidate, max-age=0

我也尝试过添加以下元标记，但没有奏效.

I have also tried by adding the following meta tags and it didn't work.

<META HTTP-EQUIV="CACHE-CONTROL" CONTENT="NO-CACHE">
<META HTTP-EQUIV="PRAGMA" CONTENT="NO-CACHE">

请帮忙

推荐答案

我已经尝试过像下面这样设置标题，效果很好！

I have tried by setting header like below and it worked like a charm!

header("Cache-Control: private, must-revalidate,
        max-age=0, no-store, no-cache, must-revalidate, post-check=0, pre-check=0"
      );
