Perhaps "[no] cache-control no-cache" ? This way we can add
more directives in the future, and also allow location specific
configuration. E.g., 

server "example.com" {
	listen on * port 80

	gzip-static
	no cache-control no-cache

	location "/hotstuff/*" {
		cache-control no-cache
	}
}

alternative approach would be to provide some generic mechanism to set
HTTP headers (send-header?), then operators can just do whatever they
need to do without patching httpd?

server "example.com" {
	listen on * port 80

	gzip-static

	location "/hotstuff/*" {
		send-header "Cache-Control: no-cache"
	}
}
