IE8 doesn't show open/save dialog when opening PDF

I have written Java application that, when user click on the button, it
opens new location in the same window in which it shows new HTML page
and opens new popup window using window.open() JavaScript code. In the
popup window Java outputs PDF using following headers:

ContentType - application/pdf
ContentLength - 1000
Content-Disposition - attachment; filename=My.pdf

With above settings IE8 doesn't show open/save dialog for my PDF. Above
code works fine with IE6, IE7 and Firefox. If I change "attachment" to
"inline", then IE8 shows PDF in the popup window, but this is not what I
want. Tested on two PCs and with Acrobat Reader and Foxit PDF clients.

I tested this on IE8 and it works fine.
(without the fake contentLength)

So it probably is some setting that you changed.

Rob, very kind from you but...

I have a php script on my website that, for each .pdf file, allows the user
the choice to just open it or to offer it for download. In that case
these headers are added:

header('Content-Type: application/pdf');
header('Content-disposition: attachment; filename="'.$file.'"');
header('Last-Modified: '.gmdate('D, d M Y H:i:s',filemtime($file)).' GMT');

It works fine. Also with IE8. I get a popup that allows me to open,
save, or cancel.
When using the other option, I omit the Content-disposition header and
it opens in the Adobe Reader plugin without asking questions.

No problem in IE8 apparently. Maybe a problem in your site or in your
settings of IE8.
