caching

Good afternoon!
I looked at https://developers.google.com/speed/pagespeed/insights/ - site loading speed, and the main recommendations were - use the browser cache.
not quite clear what and how? For example, the site has the WP Super Cache plugin. Advice on how to slow down your website loading speed

Answer 1

In WP Super Cache settings there are such settings. You can use it with confidence.
Can be added manually in .htaccess file

# Create expires headers
<FilesMatch "\.(ico|jpg|jpeg|png|gif|js|css|swf)$">
ExpiresActive on
ExpiresDefault "access plus 30 days"
Header unset ETag
FileETag None
</FilesMatch>
# End Create expires headers
