In the case of IE the cache entry remains the same (it only updates
'last access' and 'last check', but never 'expiry time' (sorry if these
titles are not correct, I'm using an Spanish IE and I've transate them
directly)
Thanks,

Thanks again, Joshua.
You are right, it's my application that set 'must-revalidate' header.
But it's not the problem, I've deleted it and all works exactly the
same.
I suspect the 304 return code is the reason because Firefox set
'1970-01-01 01:00:00 (already expired)" expiry date, and not that
header.
I've found a "half-solution". If I use a 'Header append Cache-Control
"max-age=something"' , Apache inserts this header in response, even if
return code is 304 (until now I've used only 'ExpiresByType' to set
cache-related headers).
In this case, if Internet Explorer 6.0 receives max-age header, it
updates correctly cache-entry expiry time, but Firefox still updates it
to '1970-01-01 01:00:00 '. I'll search a litte more....
I'd like to see full request/response headers for these cases
(original and 304), because I can't really believe that MSIE and
firefox are broken enough to not properly update their cache on a 304
in the typical case.
Joshua.
