[Zope] Generating text/csv from DTML method, Mime Type?

[Farrell, Troy]

I know this sounds silly, but try making the url end with .csv
I wrote a perl cgi script some time ago that spit out a csv file.  When it
ended with .csv, IE seemed to ignore the server's Content-type: text/html
header.

Look, my stock is falling!  Actually, if you look at the link below and to
the right of the table, you'll see a download spreadsheet link.  Yahoo uses
a &e=.csv to set the extension.  Presumably, the e value is for extension.

FWIW, I recently had to support a customer in downloading files for
use by spreadsheet software. After a little investigating, especially
at the IETF web/FTP site, I discovered that there is no registered
MIME type "text/csv". Can anyone refute this?

There is a registered MIME type "text/tab-separated-values". Based on
something I read recently on the Zope site, it may be that if you set
the MIME type to application/vnd.ms-excel but send a tab separated
values file, excel will open it. I haven't tried this though.
