Hi Larry, we are having problems with our DNS, so I cannot post to the list
as it thinks it is coming from another address than I signed up with. 

Anyway, the answer to your problem is to set the Content-Disposition header.
Here is an example:

<% response.setHeader("Content-Disposition", "attachment"); %>

This is in its simplest form. You can also specify the name of the file you
want the o/s to use by default for the saved file and provide the file size,
among other things. I believe the file size just allows windows to calculate
the download time remaining for very large files. Example:

<% response.setHeader("Content-Disposition",
     "attachment; filename=myFile.txt; size=1234"); %>

Here is the rfc on the content-disposition header

If you would be so kind, could you post this to the list for others who may
find this information useful? Thanks.

Here's what I think should be a simple question, but I could not find the
answer.
I have a servlet that generates dynamic content in text/plain format that
the end user really does not want to display in his/her browser, but really
wants to accept it as a download file. If you click on my link to the
servlet, currently it builds the data and displays it in text in the
browser.
Of course the user could right click and do "save file as" to stream it
directly to a file on his/her hard drive, but that is not elegant. How do I
make the servlet automatically bring up the save file dialog?
Thanks,
Larry
