[OpenLayers-Users] How to force browser to download a file with a OpenLayers request response

[Phil Scadden]

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.
