Wordpress how to server all static files under wp-includes from a subdomain?

how to server all static files under wp-includes from a sub domain ? Right now if the site is www.example.com then the static files are from http://ift.tt/1YVhA5c... Want it from http://ift.tt/1XtQvai... I guess its an update from wp-options table ? Any experience ?
