can you give an example of the actual HTTP response headers that are sent to the client?

I just tested that the following response works with IE8 on WinXP and IE10 using its IE8-Mode on WIndows 8:

HTTP/1.1 200 OK
Transfer-Encoding: chunked
Content-Type: application/x-zip-compressed
Server: Microsoft-IIS/7.5
Content-Disposition: attachment; filename=Portal.zip
Date: Mon, 03 Jun 2013 18:14:14 GMT

[...]

This is generated by a Servlet on Tomcat 7.0.40 that sets the Content-Type and Content-Disposition headers and then writes bytes to the respone's OutputStream (the response is served by IIS/7.5 using ISAPI Redirector). For Content-Disposition, I'm using javax.mail.internet.ContentDisposition which should automatically add necessary escaping and quoting to the "filename:" part.

I also tested with IE10's IE7-Mode that is used when activating Compatibility View and no X-UA-Compatible header is present that tells IE to use it's highest browser mode (like "X-UA-Compatible: IE=Edge").

(As an aside, for my websites I don't support any IE below IE9... ;-)  However, I use the "X-UA-Compatible: IE=Edge" header to prevent IE to use the compatibility mode, which can happen if Microsoft suddenly decides to add your site to its "compatibility view list", or sometimes if IE is embedded as ActiveX control etc...)
