This should get you started:
from tg import expose, response
from tg.controllers import CUSTOM_CONTENT_TYPE
@expose(content_type=CUSTOM_CONTENT_TYPE)
def download__file(self):
rh = response.headers
rh['Content-Type'] = 'application/octet-stream; charset=utf-8'
#response.content_type = 'application/octet-stream'
disposition = 'attachment; filename="filename.ext"'
rh['Content-disposition'] = disposition
rh['Pragma'] = 'public' # for IE
rh['Cache-control'] = 'max-age=0' #for IE
return "these are the file contents"
HTH,
