I implemented a method on my subclass of WASession that allows me to easily send a file in response to a button or link click.

UserSession>>download: contents mimeType: mimeType filename: fileName
	self respond:
			[:url |
			| response |
			response := WAResponse new.
			response contentType: mimeType.
			response headerAt: 'Expires' put: 'Thu, 01 Jan 2095 12:00:00 GMT'.
			response headerAt: 'content-disposition'
				put: ('attachment ; filename=' , fileName).
			response headerAt: 'Content-length' put: contents size.
			response contents nextPutAll: contents.


I use it for CSV file downloads.
