Hi,
I actually just got this working and the answer is unbelievably bizarre.
It all sorta boiled down to the Pragma header. I can't set the pragma
header in my servlet and must do it in the Apache httpd.conf like this:
Header append Pragma "blah"
And "blah" could be anything and would still work, it's just the fact
that it's set in the Apache httpd.conf! Weird, this isn't scientific, I
must be missing something. :)
Here's the combo I got it working with:
Pragma: no-cache, blah
Cache-Control: private
Content-Length: sizeof(stream)
Content-disposition: attachment; filename="doc.pdf"
Regards,
Daniel
