We did something like this too. We have a html/fax generation code that
turns our XML data and XSL into rtf. We then set the contentType =
"application" before sending the file back. This allows the pop-up dialog to
appear (to save the file). Also, if you set the contentType to "text/rtf" it
will be displayed directly in MSIE (and I think it requires a plugin..or
loads MS-WORD if your using Netscape).
The question I have is..when sending a file back to be "saved" by the user,
how can you set the filename that appears in the pop-up dialog?
