I don’t know anything about IE9, but those file formats can carry virus
and trojan payloads. Maybe it’s a security setting in IE9?

My car is Japanese. My Vodka is Russian. My pizza is Italian. My kebab is Turkish. My democracy is Greek. My wine is French. My coffee is Brazilian. My language is English. My movies are American. My music is African. My beers are German. My shirt is Indian. My oil is Saudi Arabian. My electronics are Taiwanese. My rifle is Czech. My shoes are Chinese. My math is Arabic, my writing Latin. And you complain that your neighbor is Mexican?

I click on an attachment in RT, nothing happens. I right click save
the attachment, IE gives an error stating the file couldn’t be
downloaded. I am just worried since IE 9 has finally hit RTM and I’m
sure someday it will be part of Windows Updates and these users will
not be able to download attachments.

I found this link: http://support.microsoft.com/kb/316431

Is RT in anyway setting pragma: no-cache in the headers?

If only I can have all these users use Firefox then there would be no issues.

My Setup:
CentOS 4.9
MySQL 4.1.22
Perl v5.8.5
httpd-2.0.52 + FastCGI

That article refers to SSL, you don’t say if you’re using SSL.
RT shouldn’t be setting it, but you can always confirm that with
Firefox by looking at the headers.

I apologize, I am using SSL on our RT.

Sure enough according to Firefox our server is setting Pragma:
no-cache in the headers. Now to investigate how to turn this off on
Apache if RT is not setting it…

Cache-Control:no-cache
Connection:close
Content-Type:text/html; charset=utf-8
Pragma:no-cache

Set-Cookie:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx; path=/

Hi list,

I think RT is writing these headers
here’s what is see in html/Elements/Header

$r->headers_out->{‘Pragma’} = ‘no-cache’;
$r->headers_out->{‘Cache-control’} = ‘no-cache’;

you can try to modify this file and see if it resolves the problem

Regards,

here’s what is see in html/Elements/Header

Except that attachments are served from a dhandler that doesn’t invoke
Elements/Header

oh yes, my bad
just test and I didn’t see the “no-cache” headers while downloading an
attachment with my configuration

these headers could also be set by firewall, proxy, not necessary apache

FYI: I just tried on our rt 3.8.9 with ssl and IE9 downloaded fine PDF
attachments from my tickets.
