htaccess设置了js的到期日

Question

我在我的htaccess中使用下面的代码用于杠杆浏览器缓存,它为javascript设置了1个月的到期但是当我测试这个google页面速​​度洞察时它要求增加各种js到期并且它显示设置为2天默认为什么它发生？

尝试设置:

ExpiresActive On
ExpiresByType text/javascript "access 1 month"
ExpiresByType text/x-javascript "access 1 month"
ExpiresByType application/javascript "access 1 month"
ExpiresByType application/x-javascript "access 1 month"
ExpiresByType application/json "access 1 month"          // Thanks to David Goss
