"setHeader" is for adding a http response header to the response. One cannot use "" to surround the value part

The header name and the value are separated by white spaces (space or tab)

Notes: If a response includes both an Expires header and a max-age directive, the max-age directive overrides the Expires header, even if the Expires header is more restrictive.
