OK, I'm getting closer. I found this post by Flemming Adersen.

I too have the same problem when I use https, and can only get it to
work with http. Also, I can only get the save dialog to come up if I
set the content type to "application/anything", where anything can
literally be anything. If I set it to "text/plain", it still displays
the file in the browser.
The other problem with this is it wants to save the file as an a4d
document. I have to name my txt document an a4d document so that <%set
content type("application/anything")%> is parsed out on the server. I
suppose I could set A4D to parse txt documents also, but is there a way
to set the content type from outside of the document being served??
I've used other websites where I can download/save a text document with
a normal left click, so I know it's possible!
Thanks,
Jason
