How to Set an Expires Header in Apache
Setting an Expires (or Cache-Control) header in Apache will help speed up your Web site. We’re running Apache 2.x, and define an expires header for all of our static assets (images, stylesheets, and scripts).
Just add the following to your <VirtualHost> section of your Apache configuration:
ExpiresActive On
ExpiresByType image/png “now plus 365 days”
ExpiresByType image/jpeg “now plus 365 days”
ExpiresByType image/gif “now plus 365 days”
ExpiresByType application/javascript “now plus 365 days”
ExpiresByType application/x-javascript “now plus 365 days”
ExpiresByType text/javascript “now plus 365 days”
ExpiresByType text/css “now plus 365 days”
You can read all about expires headers by reading Yahoo!’s Best Practices for Speeding Up Your Website guide.
