This really should be tested, but as far as I can remember it did serve 
from cache rather than rerequest. Its been some time since I did this 
(and at another company) and unfortunately I cant remember this too 
clearly... From the 'CacheIgnoreCacheControl' at least it does sound 
like it would ignore the spec and serve cached content though.
