W3TC and minify cache headers

I’m still loving easyengine, when I start looking through all the .conf files are see all the important settings you are making to optimize for just about any wordpress option it’s great. I’m using a basic setup with wpfc for cache and w3tc for database caching. I was messing around with minify settings for w3tc and it seems to work for me. The only thing I notice is a Google pagespeed test says there are no cache control headers for any of the minified css and js. I’ve been doing a lot of looking and I can’t figure out why caching headers aren’t being set on minified files. Do you have any ideas? Thanks.
