I am using the latest version of WordPress MU and W3TC.
I have a self-hosted CDN (basically a CNAME into a separate directory), and the images, css, and theme files that are uploaded are missing the expiration.
Message from Google
The following cacheable resources have a short freshness lifetime. Specify an expiration at least one week in the future for the following resources
1. Is it adviseable to have a CDN, even though it is the same server? I am under the impression that a browser can only load 8 items simultaneously and a self hosted CDN, at the least, allows the browser to load more things at once.
2. I have enabled all the checkboxes in Browser Cache except for
Prevent caching of objects after settings change Disable cookies for static files
and I am using the option
cache with max age (public, max-age="EXPIRES-SCEONDS")
Expires header lifetime: 31536000 seconds
What am I missing?
Again, this is multisite
