Gau*_*ral 6 etag joomla caching cache-control pagespeed
我想在谷歌建议的joomla网站中使用Cache Control和ETag.但不知道该怎么做.我搜索了很多,但找不到任何可怕的例子.
任何人都可以告诉我该怎么做.. ??
对于缓存控制我已经找到了这个例子,但这是完整的语法.. ?? 以及将它放在文件<head>标签中的位置index.php??
另请告诉我ETag的语法以及编写它的地方.

使用文本编辑器，将以下内容添加到您的.htaccess文件中
编辑 如果您的目标是专门提高您的YSlow得分，并且您没有将这些标签用于其他目的，则最好将以下ETag设置为：
FileETag none
