[Zope] - RESPONSE.headers Help needed

[BScherer@mobile.bam.com]

I'm using the following: 

RESPONSE.headers['Content-Type'] =  "text/csv"
RESPONSE.headers['Content-Disposition'] = "inline; \
filename=salesdat.csv"
RESPONSE.flush()

in an attempt to get the browser to prompt the user to save the file to disk instead of displaying it in the browser.

Problem is, the browser always displays the file.  I've checked that the expected headers are coming through with a sniffer, and they are.  I expect I'm not producing the headers right, or what I want to do isn't possible.

Any ideas?

TIA
