There supposedly is a way the fast download function(web2pyslices)
def fast_download():
# very basic security (only allow fast_download on
your_table.upload_field):
if not request.args(0).startswith("db.your_table.your_field"):
return download()
# remove/add headers that prevent/favors client-side caching
#7days
response.headers['Cache-Control'] = "max-age=604800"
del response.headers['Pragma']
del response.headers['Expires']
filename = os.path.join(request.folder,'uploads',request.args(0))
# send last modified date/time so client browser can enable client-side
caching
response.headers['Last-Modified'] = time.strftime("%a, %d %b %Y %H:%M:%S
+0000", time.localtime(os.path.getmtime(filename)))
return response.stream(open(filename,'rb'))
this is the version I'm experimenting with. the original had a del Cache
Control instead of the max age. but google pagespeed still tells me that no
expiration date is set.
