Uploaded Font cacheing

I downloaded an OTF file from Font Awesome and uploaded it within the settings of my project. Everything works seamlessly - except it is a 600 kb file and my .htaccess cacheing doesn’t do anything since the file is hosted by you guys.

Since I am hosting the site myself, and you are hosting the OTF file, what can I do? Is there a good way to host the OTF file myself instead, without having to modify code after using the editor?
