“This tutorial explains how you can configure Lighttpd to set
the Expires HTTP header and the max-age directive of the
Cache-Control HTTP header of static files (such as images, CSS and
Javascript files) to a date in the future so that these files will
be cached by your visitors’ browsers. This saves bandwidth and
makes your web site appear faster (if a user visits your site for a
second time, static files will be fetched from the browser cache).
This tutorial was written for Debian Squeeze.“I do not issue any guarantee that this will work for you!”
