Question

我一直在努力加速我的网站。

在Google上进行速度测试时出现的一个问题是“利用浏览器缓存”。我查了一下，并在我的htaccess中添加了一些代码。请参阅以下内容：

## EXPIRES CACHING ##
<IfModule mod_expires.c>
ExpiresActive On
ExpiresByType image/jpg "access plus 1 year"
ExpiresByType image/jpeg "access plus 1 year"
ExpiresByType image/gif "access plus 1 year"
ExpiresByType image/png "access plus 1 year"
ExpiresByType text/css "access plus 1 month"
ExpiresByType text/js "access plus 1 month"
ExpiresByType application/pdf "access plus 1 month"
ExpiresByType text/x-javascript "access plus 1 month"
ExpiresByType application/x-shockwave-flash "access plus 1 month"
ExpiresByType image/x-icon "access plus 1 year"
ExpiresDefault "access plus 2 days"
</IfModule>
## EXPIRES CACHING ##

这对我的一些文件有效，但不是全部，我仍然收到一条消息，说明我的js和css文件没有设置为过期。有人可以帮忙吗？我犯错的是他们没有过期？以下是来自Google的错误消息，即使是htaccess中的先前代码。

查看上面的代码有一些缺失：

ExpiresByType text/javascript "access plus 1 month"
ExpiresByType application/javascript "access plus 1 month"
ExpiresByType application/x-javascript "access plus 1 month"
ExpiresByType text/javascript "access plus 1 year"
ExpiresByType application/x-ico "access plus 1 year"
ExpiresByType image/icon "access plus 1 year"

Facebook .js文件不是像其他人那样可以解决的，因为它是一个外部文件......你可以使用cron来解决这个问题，这基本上就是存储该文件并在本地加载它。您会发现Google Analytics，Lead Forensics等问题也存在同样的问题。

如果您想尝试使用cron，请查看本指南：http://diywpblog.com/leverage-browser-cache-optimize-google-analytics/

虽然我认为这是毫无意义的，特别是在谷歌分析方面......他们并不会因为自己的软件而惩罚你！
