i've got 99/100 score in a site but there's a persistent message about Leverage Browser Caching that not allows me to get 100/100.
Someone knows how to solve it?
The below code tells browsers what to cache and how long to remember it. It should be added to the top of your .htaccess file
<IfModule mod_expires.c>
ExpiresActive On
ExpiresByType image/jpg "access 1 year"
ExpiresByType image/jpeg "access 1 year"
ExpiresByType image/gif "access 1 year"
ExpiresByType image/png "access 1 year"
ExpiresByType text/css "access 1 month"
ExpiresByType application/pdf "access 1 month"
ExpiresByType text/x-javascript "access 1 month"
ExpiresByType application/x-shockwave-flash "access 1 month"
ExpiresByType image/x-icon "access 1 year"
</IfModule>
