I've handled this kind of thing by creating a hidden iframe and pointed
source to the file - it then asks where to send.
<iframe id="downloadFrame" style="display:none"></iframe> in html
This in the code:
var ifrm =
document.getElementById('downloadFrame');
ifrm.src =
'../lib/download.jsp?filename=' + filename + '&filetype=xls';
The download.jsp just does;
response.setContentType("application/octet-stream");
response.setHeader("Content-Disposition","attachment;filename=\"" +
filename + "." + filetype + "\"");
and then reads the file and writes to response output stream. I guess
that is simple enough to do in python too.
