Apache - Force caching dynamic PHP content with mod_headers
Normally you want dynamic content to be fresh and not catchable. But sometimes it may be useful to cache it, like when you have website behind reverse proxy. To do this try something like this: <filesmatch "\.(php|cgi|pl)$"> Header unset Pragma Header unset Expires Header set Cache-Control "max-age=3600, public" </filesmatch> Sources http://www.askapache.com/htaccess/speed-up-your-site-with-caching-and-cache-control.html external link
