强制刷新HTML文档的浏览器缓存

本文介绍了强制刷新HTML文档的浏览器缓存的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

网站被意外缓存在浏览器中大约一个月，设置了Expires和max-age标头。 缓存资源是 text / html 和根 / 。

A website was accidentally cached in the browser for about a month with Expires and max-age headers set. The cached resource is text/html and the root /.

新鲜度验证应按预期使用下一个请求中的If-Modified-Since 标头。但不知何故，很多IE用户（包括IE11）都没有获得新版本，因为浏览器没有提出请求。

The freshness validation should work as expected with the If-Modified-Since header in the next request. But somehow a lot of IE users (incl. IE11) don't get the new version anymore, as the browser doesn't make the request.

很容易破产像CSS这样的资源的缓存，但如何为文档/网站本身做这个？我不能只改变URL。

It's easy to bust the cache for resources like CSS, but how to do this for the document/website itself? I can not just change the URL.

推荐答案

添加.htaccess或apache配置

Add in the .htaccess or apache config this

ExpiresActive on ExpiresByType text/html "access plus 0 seconds"

取自 h5bp apache配置。如果您使用其他服务器软件，请查看所有 h5bp server-configs repo 以获取类似代码。

Taken from h5bp apache config. If you use some other server software, checkout all h5bp server-configs repo for similar code.
