Add Expires Header in Rails

Now I am trying to implement High web site performance following YSlow rules. In terms of Expires Header, I have configured in nginx like the following:

if ($request_uri ~* "\.(ico|css|js|gif|jpe?g|png)\?[0-9]+$") {
    expires max;
    break;
}

Yes, I got the good result because I could not see css and javascript files followed by timestamp at the end of file any more and it passed, but I still have problems with images which are retrieved from another domain. They still have no expires. Anyone knows how to deal with this problem? Thanks!

You can't affect the expires headers of images served from other domains; the configuration of those assets is up to the administrator of the domain that is serving them.
