IE 5 Cache Security Problem

[Derek Au]

HTTPS files delivered by IMP are being cached for 24 hours by IE 5.  I
couldn't find a conclusive fix in the list archives.  For instance,
turning on the "do not save encrypted pages to disk" option is IE is not
recommended in numerous threads (for file downloading, I believe).  And
I cannot find the default->cache_pages in defaults.php3, but I assume the
default is not to cache.

Does anyone have a solution?

Thanks and sorry if I missed the answer in the archives..
