Rocket Loader Expires Headers

Dear All

I use Cloudflare with caching setting respect expires headers. And my expires headers on .htaccess is more than 1 day. But when I check it on GTmetrix, I got a warning:

There is 1 static component without a far-future expiration date.

How to fix it?

You can only set expire headers for your domain hosted script. Rocket loader is hosted at cloudflare, you can not change expire headers for third party script.

I see. I just curious if we can setting expires headers for rocket loader on Cloudflare dashboard.
