[Seaside] Making a download page

[Ricardo Jacas]

im still stuck :/ , the download works but the result is an empty file
with the right name.. i give my code below:

	self requestContext
		respond: [ :response |
			response
				contentType: (MIMEType forFileNameReturnSingleMimeTypeOrDefault:
file fileName);
				attachmentWithFileName: file fileName ]

where file is an url
