Specify a cache validator

    Firstly, using a combination of GTMetrix and W3 Total Cache I’ve got things set up to run really well (with the exception of minifying CSS seems to break some of the layout, but that’s for a different post).

    I just have one issue where I get a D for “Specify a cache validator” in Pagespeed, even though I have the “Set entity tag (eTag)” setting checked in W3.

    The error is “The following resources are missing a cache validator. Resources that do not specify a cache validator cannot be refreshed efficiently. Specify a Last-Modified or ETag header to enable cache validation for the following resources”

    Any ideas how I can get this to a an A rating?

    Thanks in advance for any help.

    Are you sure that your server supports eTag?

    I have this problem as well. GT metric give me a Page Speed poor grade on account of cache validators. I’ve configured W3 Total Cache pretty extensively now, but can’t seem to make this part of my config happy, as well as YSlow which is also complaining about Add Expires headers.
