SPUG: Content-Dispostion http header

[Dan Ebert]

I don't know if I can use the URL-filename method.

I don't know the name of the file until I get the data from the form, and
the form is where the URL that calls the script is.

It was suggested that I forward the script to itself with the file when
the form is submitted (since I would then know what the name is).

This would probably work in most cases, but the form being submitted is a
file upload form (multipart form) and I think the redirect would mess up
the file upload.  (I haven't tried it though :)

Essentially the script takes a text file (uploaded by the user) tweaks it
adds some stuff and spits back an Excel file.  I want to avoid writing the
file to the server, so I was writing it out to STDOUT so the user can just
save it on their box.  (Rather than saving it to disk and giving them a
link to download it, or emailing the file to them.)

Oh, well.  It works in Netscape, and will only be used by one person
anyway.  I'll tell him to use Netscape :)

Dan.
