我从Google速度测试中得到了这个错误:
以下可缓存资源具有较短的新鲜度生命周期。为以下资源指定至少一个星期后的过期时间:

我应该在我的htaccess文件做些什么吗?
看起来静态文件没有过期设置。阅读- http://www.absolutelytech.com/2010/08/02/howto-add-expire-headers-to-cache-static-files-using-htaccess/
你需要把下面的代码放到你的。htaccess
中# Turn on the Expires engine
ExpiresActive On
# Expires after a month client accesses the file
ExpiresByType image/jpeg A2592000
ExpiresByType image/gif A2592000
ExpiresByType image/png A2592000
ExpiresByType image/x-icon A2592000
ExpiresByType text/plain A2592000
# Good for one week
ExpiresByType application/x-javascript M604800
ExpiresByType text/css M604800
ExpiresByType text/html M604800
pagesspeed:利用浏览器缓存每次浏览器加载网页时，它都必须下载所有的网络文件才能正确显示页面。这包括所有的HTML, CSS, javascript和图像。
要启用浏览器缓存，你需要编辑你的HTTP头来设置某些类型文件的过期日期。
找到你的。htaccess文件在你的域名的根目录，这个文件是一个隐藏的文件，但应该显示在FTP客户端，如FileZilla或CORE。您可以使用记事本或任何形式的基本文本编辑器编辑htaccess文件。
