Leverage Browser Caching for Images, CSS and JS

To leverage your browser’s caching generally means that you can specify how long web browsers should keep images, CSS and JS stored locally. That way the user’s browser will download less data while navigating through your pages, which will improve the loading speed of your website.

To enable it, add those lines to 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”
ExpiresDefault “access 2 days”
