htaccess for Leverage浏览器缓存不起作用

Question

我在利用浏览器缓存时遇到问题.我创建了这个.htaccess文件,并在我的服务器上使用它,但它似乎没有工作,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错误,所以任何帮助都会很好.这里有一些细节.我正在研究一个子域,我们称之为"sub"和主域"example".所以我希望http://sub.example.com/中的所有内容都能用于htaccess文件.在我的服务器上,我将.htaccess文件放在sub的主目录中,例如,它与主要目录分开.

我正在运行一个apache2服务器,同时启用了mod_headers和mod_expires.

干杯.

看起来很乱.

你也有冗余的规则,比如

ExpiresByType application/javascript "access plus 216000 seconds"

和

<filesMatch "\\.(js|js.gz)$">
Header set Cache-Control "max-age=604800, private"
</filesMatch>
