当网站有“pragma：cache”时，有没有办法强制浏览器刷新？

Question

I have once wrongly set as pragma: cache header on my website, and now I have turned it back to Pragma: no-cache, but I am still receiving reports that people don't see the updates on my site.

Is there any way to solve it?

Answer 1

It depends on what you want the users to see without force refresh. If it is the standard JS and CSS files. Do something like below -

JS

<script src="file.js?version=<?php echo $random_number;?>"></script>

CSS

<link rel="stylesheet" type="text/css" href="style.css?<?php echo $random_number;?>" />

Hope that helps.
