Specify cache validator for non-wordpress resources? (2 posts)

    Installed and setup w3tc last night (switched from Quick Cache) and seem to be having good results; raised my google page speed from average of 80 to 85-87. I wanted to see what else I could do so I tested it in Pingdom (got 80/100) and now I'm going through the items I can fix.

    Here's one:

    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:

    (two examples:)
    http://i4.ytimg.com/vi/kijwc1DTuM0/hqdefault.jpg
    http://w.sharethis.com/button/buttons.js

    Is there a way to specify a cache-validator for these non-wordpress resources? Maybe in .htaccess?

    Those are 3rd party resources, so I don't think it's possible.
