How To add to HTTP Header Response for a particular filetype

[bsaxon]

I would like to add the following to the HTTP Header Response for PDF files served by Zimbra:

Content-disposition: Attachment

Can anyone give me any insight on how to do this?

A description of the issue I am trying to resolve is available here: Links in Documents vs. Email; fix needed to solve problem opening links to PDF files

Yes, another fix would be to change browser settings to not use the plugin and prompt the user on what to do (like Open With... or Save to a location or even automatically save to a location). But I need a fix at the Web Application/Server Level. I have 700 users; none are on a Windows Domain; spread across 14 states and 95 locations; so I can't do any kind of fix across all of my user computers easily liking using a logon script or group policy or anything like that. Anybody have any suggestions here?

I found a fix that can be achieved at the Web Application/Server Level (instead of changing a client setting). See above post about changing the HTTP Header sent by the server. Anyone know how this could be achieved?

Right now, I only need to apply this fix to one Zimbra Account (where the wiki page is stored, along with the attached PDFs).

I have a good mix of IE and Firefox users (maybe 50/50).
