我已将以下代码添加到我的.htaccess中,但PageSpeed Insights仍显示Leverage Browser Caching建议.
<IfModule mod_expires.c>
ExpiresActive on
ExpiresDefault "access 1 month"
ExpiresByType image/x-ico "access 1 year"
ExpiresByType image/jpg "access 14 days"
ExpiresByType image/jpeg "access 14 days"
ExpiresByType image/gif "access 14 days"
ExpiresByType text/html "access 2 day"
ExpiresByType text/css "access 2 days"
ExpiresByType image/png "access 1month"
ExpiresByType text/x-javascript "access 1 month"
ExpiresByType application/javascript "access 1 month"
ExpiresByType application/x-javascript "access 1 month"
</IfModule>
