 * I have set expires header checked in W3 Total Cache and I can see that they are
   set in my htaccess file, but YSlow is giving me an F on expires headers. Any 
   ideas how I can rectify this? My site is audaryadairy.com.

 * Yslow reports the main culprit to be timthumb. I tried using the most current
   version of timthumb, which is supposed to have fixed the expires headers problem,
   but to no avail.

 * I just noticed that YSlow is saying that timthumb’s cache expires on 1981/11/
   19. Any idea how an expires header could be set to a date in the past?
