GTMetrix is telling me to "specify a cache validator". How do I do this?

#1

It’s telling me to do this for the images on the page. I did some googling but it doesn’t seem like there’s a definitive answer out there. I’m using CF + W3 Total Cache plugin on WordPress. Is this something I need to change through CloudFlare or W3?

#2

Hi @user7033, suspect it’s something in your .htaccess file, do you recall editing that? Can you share the contents of that file here?

#3

Sure, here is my .htaccess file:

Redirect old URLs

RedirectMatch 301 /portfolio-item/(.) /project/$1
RedirectMatch 301 /projects/(.
) /project/$1
