Added
response.setHeader("Pragma", "cache");
response.setHeader("Cache-Control", "cache");
And now it works.
I was not adding the cache-control, something else must have but did not
override my setting to cache.
Mozilla still double downloads, but then 90% of my users are IE.
Thanks.

Bert,
I just ran across something similar today, read this document:
http://support.microsoft.com/default.aspx?scid=http://support.microsoft.com:
80/support/kb/articles/q316/4/31.asp&NoWebContent=1
The way I understand it, IE wants to save the file in cache before letting
you view it; if you're requesting something via SSL (https://...) IE
actually honors the cache defeating tags, which I noticed you have; hence
the error. Removing the...
> Pragma: No-cache
> Cache-Control: no-cache
...headers should fix your problem, I think. It worked for me, let me know
if this words for you too.
