緩存過期標題CSS和JS不工作

Question

我剛剛嘗試加快我的網站。

當我在Google中進行速度測試時出現的問題之一是「利用瀏覽器緩存」。我看了這個，並添加了一些代碼到我的htaccess。請看下面：

## 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 ##

這工作對我的一些文件，但不是所有的人都和我仍然得到我的JS和CSS文件的載荷不會設置爲過期的消息。有人可以幫忙嗎？我做錯了什麼，他們不過期？這是我的谷歌錯誤信息，即使使用htaccess中的先前代碼。

看你上面的代碼有一些缺失：

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的.js文件是不是你將能夠解決其他人一樣，因爲它是一個外部文件...你可以使用cron來解決這個問題，它基本上存儲文件並在本地加載它。你會發現你有東西像谷歌分析了同樣的問題，鉛取證等等等等

如果您想在使用cron嘗試，然後看看這個指南：http://diywpblog.com/leverage-browser-cache-optimize-google-analytics/

雖然我覺得它是非常沒有意義的，特別是當談到Google Analytics時......他們不會因爲自己的軟件而懲罰你！
