Force cache of HTTPS?

Hello,

I have to force the cache of images, CSS and JS files on a web site
accessed through HTTPS. I tried adding the correct "Expires" and "Cache
control" HTTP headers (for cache control I imposed the max-age and
public) without getting those files to be used from cache. I checked
using the openssl client that the headers are corecttly sent to the
client and all seems to be ok. It seems IE discards those headers and
doesn't cache anything it get through HTTPS.
I managed to activate the cache only by disabling the check "Do not
save encrypted pages to disk" from the Advanced configuration of IE.
With that option unselected the files are cached corectlly. I thought
that check was suppose to do what it show: blocks the saving into the
disk cache of https pages, but IE should continue to use the memory
cache to store the https content (especially for those pages where the
HTTP cleary instructs so) and use those pages in the memory cache...
Does anyone know a header or configuration that allows forcing the
cache of https pages in IE? I need to cache that content and due to
different companies policies (mostly banks) the disabling of that check
is not an option. Is there any other way to get IE to cache content
obtained over https?

Thanks a lot,
Florin Bota.
