Question

I have the following code in my wordpress .htacces

    ## EXPIRES CACHING ##
<IfModule mod_expires.c>
ExpiresActive On
ExpiresByType image/jpg "access plus 1 year"
ExpiresByType image/jpeg "access plus 1 year"
ExpiresByType image/gif "access plus 1 year"
ExpiresByType image/png "access plus 1 year"
ExpiresByType text/css "access plus 1 month"
ExpiresByType application/pdf "access plus 1 month"
ExpiresByType text/x-javascript "access plus 1 month"
ExpiresByType application/x-shockwave-flash "access plus 1 month"
ExpiresByType image/x-icon "access plus 1 year"
ExpiresDefault "access plus 2 days"
</IfModule>
## EXPIRES CACHING ##

However its not working, im still having lots of caching errors in Google Pagespeed.

Answer 1

Your syntax is fine. If it isn't working, mod_expires can't be enabled.

• Enable mod_expires: a2enmod expires
• Restart Apache: /etc/init.d/apache2 restart

Answer 2

Try this:

# Enable browser caching for most static assets, 1 month
<filesMatch ".(css|jpg|jpeg|png|gif|pdf|js|ico|svg|ttf|woff|woff2)$">
Header set Cache-Control "max-age=2592000, public"
</filesMatch>

Change the max-age to the number of seconds you want. Mine is set to 1 month.

This uses cache-control instead of expires. Cache-control is the more modern solution. A good overview of the differences and how to use each is here: http://dev.mobify.com/blog/beginners-guide-to-http-cache-headers/
