How to serve static assets with an efficient cache policy in WordPress or WooCommerce

In order to serve static assets with an efficient cache policy you need to add specific code to your WordPress .htaccess file. You’ll find complete code below – it’s ready to use on any website. But first we need to find out how we’ll access tha file.

Where to locate and how to open .htaccess file in WordPress

There are few ways to get to .htaccess file. File itself is located in your hosting server – in the main WordPress directory – public or public_html It can be accessed via File manager tool in your hosting admin panel (Cpanel, Directadmin, Webmin, etc.).

If you can’t edit .htaccess via server admin panel, you may login to your server via FTP client (for example Filezilla), and edit the file there.

Once you’re there you can edit .htaccess file content without any additional tools.

How to add code to serve static assets with an efficient cache policy

When you open .htaccess file, scroll to the end of it – until you’ll see line # END WordPress.

Add static assets code before it:

<FilesMatch "\.(webm|ogg|mp4|ico|pdf|flv|avif|jpg|jpeg|png|gif|webp|js|css|swf|x-html|css|xml|js|woff|woff2|otf|ttf|svg|eot)(\.gz)?$">
	<IfModule mod_expires.c>
		AddType application/font-woff2 .woff2
		AddType application/x-font-opentype .otf
		ExpiresActive On
		ExpiresDefault A0
		ExpiresByType video/webm A10368000
		ExpiresByType video/ogg A10368000
		ExpiresByType video/mp4 A10368000
		ExpiresByType image/avif A10368000
		ExpiresByType image/webp A10368000

		ExpiresByType application/x-font-opentype A10368000
		ExpiresByType application/x-font-truetype A10368000
	</IfModule>
	<IfModule mod_headers.c>
		Header set Expires "max-age=A10368000, public"
