FIXED
Hi,
I've now changed the download function to use response.stream in order
for the Http Header 'Content-Disposition: attachment;
filename=myimg.JPG' not to be added. That didn't make a difference
except that one can now enter the image URL into the browser without
being prompted to save the file. So it's not a download function
anymore :)
Next I added these headers:
response.headers['Expires'] = 'Sun, 20 Sep 2009 12:00:00 GMT'
response.headers['Last-Modified'] = 'Mon, 10 Aug 2009 12:13:14
GMT'
response.headers['Cache-Control'] = 'max-age=3600'
But that had no effect either. Every time I revisit the page the
pictures would briefly flash (as if cached) and then start trickling
in again.
Finally this fixed it:
if request.env.http_if_modified_since:
raise HTTP(304)
