I currently have multiple Cache-Control directives in my headers.
HTTP/1.1 200 OK Server: cloudflare-nginx Date: Fri, 23 Aug 2013 14:00:13 GMT Content-Type: text/css; charset=utf-8 Transfer-Encoding: chunked Connection: keep-alive Set-Cookie: __cfduid=d9875e4c85f50153f1327d57ba3dcc6181377266412900; expires=Mon, 23-Dec-2019 23:50:00 GMT; path=/; domain=.xxxxxxxx.com Vary: Accept-Encoding,Cookie Cache-Control: max-age=30672000, public, must-revalidate Expires: Wed, 13 Aug 2014 14:00:12 GMT Last-Modified: Fri, 23 Aug 2013 10:18:55 GMT X-UA-Compatible: IE=edge Cache-Control: private, no-store, no-cache, must-revalidate, no-transform, max-age=0 CF-RAY: a2853e8a3cc3112 Content-Encoding: gzip
and REDbot is throwing up errors / warnings on the autoptize generated php files....
The ETag header's syntax isn't valid.
The max-age Cache-Control directive appears more than once.
Note: I am also using WP-Supercache, I have cache-control and expiry directives in my htaccess, and I am using Cloudflare.
What headers does Autoptimze add and do you have any advice on changes I should make?
