但在gtmetrix还在说： The following cacheable resources have a short freshness lifetime. Specify an expiration at least one week in the future for the following resources

什么是以下资源？只是CSS，一切？当你打开浏览器中的页面与开发人员工具的“网络”选项卡打开，该怎么办文件的Repsonse的Headers部分说？ – 2014-10-28 14:38:06

是否gtmetrix说哪些文件没有被缓存？ [Google Page Speed]（https://developers.google.com/speed/pagespeed/insights/）列出了没有/缓存太少的文件。 – Reeno 2014-10-28 15:05:35

尝试谷歌页面速度，它给出了相同的结果。利用浏览器缓存jpg，css，js文件 – Mareks 2014-10-28 15:14:47

您的htaccess文件的语法是否正确。请确保您

发生在正确的文件夹中的htaccess文件（即项目的根文件夹）
已安装并启用了模块指定mod_expires（见how to check if mod_expires is enabled
设定所需的到期时间你所有的资源（哪些资源被“下列资源”所占用？你已经为某些资源设置了过期标题长达一年）

感谢您的快速回复，我在终端中试过这个命令：apachectl -M mime和头文件都是共享的，不要在任何地方看到过期模块 – Mareks 2014-10-28 15:01:06

编译模块： core.c mod_so .c http_core.c prefork.c – Mareks 2014-10-28 15:51:56

如果您的列表中没有expires_module，则不会安装/启用它。要求您的提供商安装/启用它。而且，正如Reeno所说，你必须将你的.htaccess文件放到你的域指向的文件夹中。 – 2014-10-31 23:48:34
