WP Super Cache with header expires – YSlow rating

I’ve tried adding the below (from: https://gtmetrix.com/add-expires-headers.html) to my htaccess file, but no luck… anybody?

<IfModule mod_expires.c>
# Enable expirations
ExpiresActive On
# Default directive
ExpiresDefault “access plus 1 month”
# My favicon
ExpiresByType image/x-icon “access plus 1 year”
# Images
ExpiresByType image/gif “access plus 1 month”
ExpiresByType image/png “access plus 1 month”
ExpiresByType image/jpg “access plus 1 month”
ExpiresByType image/jpeg “access plus 1 month”
# CSS
ExpiresByType text/css “access 1 month”
# Javascript
ExpiresByType application/javascript “access plus 1 year”
</IfModule>

That’s the correct code. As you can see on the first line of the code, the rest of the code works only if your host has mod_expires module. Even if a host has mod_expires, there may be some limitations on how to enable it for a particular site. It’s best to check with the host on how to enable / use it.
