Drupal 7, .htaccess and mod_pagespeed

Of course I'm going to tell you that these items actually belong in your vhost.conf file(s), but just in case you don't have access to that, but your host does have mod_pagespeed enabled, here's the configuration I have running (very!) successfully with my Drupal 7 installation. In conjunction with CloudFlare, I've dropped my page loads by over 70% (almost 11s to 3s on average).
