使用一个元标记的头部会到期的所述页面
将。META HTTP-当量= QUOT;到期" ; content =" Tue，1996年8月20日14:25:27 GMT">
无用 - 不会影响CSS文件，无论如何都会被任何
真正的HTTP标头覆盖。哦，当然，任何持有
页面的人卡在他们的缓存中都不会看到新版本。
最好的解决方案是将新的CSS文件复制到新的文件名，然后将
更改为指向新的CSS。然后他们应该使用旧的CSS +旧的HTML或新的CSS +新的HTML来获得
。既然您首先更改了HTML
，它可能仍然会中断，但是从您说的人*是*
获得新的HTML很好。

这没有意义。页面在到期时会被完全解析，因此，头部中列出的脚本将重新加载为

I have updated my CSS and if you view the main page with the old css
cached, it breaks the page. Is there any way to force viewers that
have the old css cached to get the new css?
Our viewers are NOT tech savvy, and wouldn''t know what a "hard refresh"
is, nor that it needed to be done.

Use a meta tag in the head to expire the page.
<META http-equiv="Expires" content="Tue, 20 Aug 1996 14:25:27 GMT">

<META http-equiv="Expires" content="Tue, 20 Aug 1996 14:25:27 GMT">Useless - won''t affect the CSS file, and would be overridden by any
real HTTP headers anyway. Oh, and of course, anyone with a copy of the
page stuck in their cache won''t see the new version.
The best solution is to copy the new CSS file to a new filename, and
then change the HTML to point to the new CSS. Then they should either
get old CSS+old HTML, or new CSS+new HTML. Since you changed the HTML
first, it might still break, but from what you say people *are*
getting the new HTML fine.

That doesn''t make sense. A page is parsed completely when it expires,
therefore an scripts that are listed in the head will be reloaded fresh as
well. Do you have any example of how it fails?
