[Mod_gzip] Caching working with mozilla but not IE

[Matt Dickinson]

Hi,

I'm running mod_gzip 1.3.26.1a with Apache 1.3.28 and php 4.34. Things
appear to be "normal" when webpages are viewed with Mozilla, that is to say,
the output is compressed and images are cached and not reloaded each time
the page is loaded. However, when viewed with IE, the pages are compressed
as expected, but images are not cached and are reloaded each time. If you
wish to see this phenomena, have a look at http://micq.alpha345.com 

I'm kinda stuck as to what to try next, I've spent a good few hours reading
over the docs and trying different configurations out but to no avail, and
I'd be grateful if someone could offer some advise. Please find my
configuration below.

Thanks,

Matt
