After launching my web page through the Google Webmaster Tools PageSpeed analyzer, he informed me that none of my resources are cached. Below is the code in my .htaccess file, taken directly from H5BP. Do I correctly assume that the calculus below is set correctly and that something is wrong in my implementation, or do I need to set explicit expiration for each file name, rather than broad generalizations?
