When you send Expires header to browser, it will cache your response and only check for newer version after the expiration date has passed. Since browser won't check for newer version, changing your server settings won't affect browser's cached data. If you made some mistake in your script or there is an update, you can use query string to force browsers to ask for your script.

当您向浏览器发送Expires标头时,它将缓存您的响应,并仅在过期日期过后检查更新的版本。由于浏览器不会检查更新版本,因此更改服务器设置不会影响浏览器的缓存数据。如果您在脚本中犯了一些错误或者有更新,则可以使用查询字符串强制浏览器询问您的脚本。

Assume this is your current script:

假设这是您当前的脚本:

<script src="http://getapple.net/phpbb/banners.js" ></script>

What you need to do:

你需要做什么:

<script src="http://getapple.net/phpbb/banners.js?v=20150510" ></script>

Since URL is not the same, browser will ask for the one with query string and your new settings will be applied!

由于URL不相同,浏览器会询问带有查询字符串的URL,您的新设置将被应用!
