Cfcontent type excel over SSL

Question

Hi guys, I dump an excel file using
<cfcontent type="application/msexcel">
<cfheader name="content-disposition" value="attachment;filename=term.xls">
and works fine in dev (http), but once I go to production (https) Internet Explorer won't open it. I remove those headers and IE shows the html table just fine, but when I add back the excel header I get the error "Internet Explorer was not able to open the internet site. The requested site is either unavailable or cannot be found". It also works fine in Firefox.
Any work around for this?
thanks!

Depending on where you use <cfheader> it might be ignored (especially if you've ever flushed the page).
Try this first:
<cfcontent type="text/xml" reset="true" variable="#reportContent.content#"/>
if you're on a high even CF where you can set a variable in cfcontent.
See: http://support.microsoft.com/kb/323308 for more information on your problem on general.
And if you haven't, try downloading Fiddler (http://www.fiddler2.com/fiddler2/) to verify what your cache-control settings you are sending back to IE on this page.  You don't want to be sending either no-cache or no-store to the client.
Hope this helps!
