expires.url configuration for static images in lighttpd

Question

Hi all,

I am trying to avoid repeated re-loading of images from my web app. I use lighttpd to serve the static content, and I have expired configured like so:

expire.url = ( "/static/" => "access 1 years", "/static/images/" => "access 1 years")

This seems to be working for js and css, who live in /static.

But this does not really work for image files - it seems that the browser still requests them over and over again, receiving a '304 Not Modified' response.

Help anyone?
