I do a very similar thing in my application. Generate a file and serve it up to the user. So far this has worked well:<br>
downloadtext: contents named: aFilename<br>
"trigger a file download operation for aFilename with the contents in contents"<br>
<br>
self requestContext respond: [ : response |<br>
response contentType: 'text/plain';<br>
attachmentWithFileName: aFilename;<br>
nextPutAll: contents.<br>
].<br>
<br>
<br>
where "contents" is a string containing the text of the file to download<br>
<o:p></o:p></p>
