pagespeed

Hi, I have enabled caching in IIS 6 for all our static images and CSS(by right clicking on those folders in IIS and enabled Content Expiration after 30 days under HTTP Headers).

When I run Google PageSpeed, and look at the resources tab, the status of those images and css shows up as 200, but I was expecting a 304(not modified). When I checked Yahoo.com in Pagespeed, all its images have a 304 status. So my caching is not working? or is this how IIS content expiration works.

Any help would be appreciated.
