XF 1.4 Use cookie-free domains => config.php

[Betclever]

Hello all,

I'm trying to optimize my Xenforo forum and when I made a test with GT Metrix, it showed me a lot of things under "use cookie-free domain".

What must I do with this?
I have seen a lot of posts with this but shall I add some lines in the file config.php and add a subdomain?

If yes, can someone tell me what must I do to do this please?

Regards,

what is the best option in the case of cookie free domain?

Speed up your site with a CDN

You would do over 3TB per month of images and javascript delivery?

Yeah, I calculated it wrong, lol.
