GTMetrix is saying the following


#1

There are 1 static components without a far-future expiration date. - https://ajax.cloudflare.com/cdn-cgi/scripts/935cb224/cloudflare-static/rocket.min.js

It’s a wordpress site using W3TC


#2

That’s true. rocket.min.js doesn’t have a far future expiration date because is it builds itself based on the contents of the request as part of Rocket Loader to improve overall javascript performance. You can disable Rocket Loader if you don’t believe the performance gain is worth it or you can ignore the GTMetrix warning.
