I''m using mongrel as my http server. I was using yslow to evaluate the performance of my web site and noticed I was downloading the .css file on every request??? I use one .css file for the whole site and I though I would be cached? Yslow indicates that there is no expires date/time set for the css file. How can I tell mongrel to send an expires header with my static content? thanks,
