我在使用Leverage浏览器缓存时遇到问题。我已经创建了这个.htaccess文件,并在我的服务器上使用它,但它似乎不起作用,我从这里复制了这个"http://www.samaxes.com/2011/05/improving-web-performance-with-apache-and-htaccess/"。我最喜欢犯一个基本的错误,所以任何帮助都会很好。以下是一些细节。我正在处理一个子域,让我们称之为"sub",主域为"example"。所以我想要所有的东西http://sub.example.com/供htaccess文件使用。在我的服务器上,我把.htaccess文件放在sub的主目录中,例如,它与主目录是分开的。
我正在运行一个同时启用mod_headers和mod_expires的apache2服务器。
干杯。

看起来很乱。
你也有像这样的冗余规则
ExpiresByType application/javascript "access plus 216000 seconds"
和
<filesMatch "\.(js|js.gz)$">
Header set Cache-Control "max-age=604800, private"
</filesMatch>
尝试使用html5样板中的更清洁(和最新)规则,或者检查所有h5bp服务器配置
只使用这个并尝试一下:
<ifModule mod_expires.c>
ExpiresActive On
ExpiresDefault "access plus 5 seconds"
ExpiresByType image/x-icon "access plus 2592000 seconds"
ExpiresByType image/jpeg "access plus 2592000 seconds"

正如@Anthony Hatzopoulos所指出的,您正在使用重复的配置,它们可能会发生冲突。当然,如果你喜欢,你也可以使用"fileMatch"的方式,但问题是它们不是很好的代码。请注意,如果您使用"fileMatch",则不使用代码。
