How do I set expiration on CSS, JS and Images?

I have recently analysed my website with pagespeed addon on firebug. It suggested me to set expiration on CSS, JS and image files.

I am wondering, how do I do this?

Solution

  • This is the one I use to fix the exact same thing when I ran the PageSpeed Addon:

    <FilesMatch "\.(jpg|jpeg|png|gif|swf)$">
    Header set Cache-Control "max-age=604800, public"
</FilesMatch>

    This goes into your .htaccess file.
