Is it possible to serve static resources like JS files and images, without adding cooking to the response?

most web servers include litespeed, is working in this way.
the cookies are in request header, but not in response header.
Correct me if wrong.

That too without setting up separate domain or server instance for it?

base on above reason, still need separate domain to eliminate cookies, no cookie s transfer between client and server.
