[Plugin: W3 Total Cache] Compression on self hosted CDN?

I checked and there isn’t a .htaccess file on the subdomain! The subdomain is just a folder on the main domain, so I didn’t know I would need one. Clearly I seem to be wrong.

Which .htaccess file shall I put into it to make it work like it should?

I added this .htaccess file from the “Install” section of the plugin to the subdomain folder – it still didn’t send it compressed:
