I ran tests on my website using Google's PageSpeed and it recommends that I "Leverage browser caching" and provided the following resource:
This resource never explains how to actually change the expiration date of my http headers. Do I do this through .htaccess? I would like to set the caching for as long as possible (without violating Google's policy of a year max).
Any advice on recommended settings (for a custom php-driven social networking community) would be greatly appreciated.
