When doing SEO tests, we consistently seeing a message for cache headers on images. We were thinking of implementing but cannot find the appropriate way to test this as the x-cache still gives a MISS.
Below is the htaccess file we have to accommodate for adding cache header for images.
How can I test to see the performance gain if I did this?
# One month <filesMatch ".(css|jpg|jpeg|png|gif|js|ico)$"> Header set Cache-Control "max-age=2628000, public" </filesMatch>
