How to set Keep alive in appspot.com

How do I get keep alive enabled for the cdn images?

Just set up an ‘application’ at https://appengine.google.com/ and uploaded images. Was following instructions from
http://www.labnol.org/internet/host-website-on-google-app-engine/18801/

and using the linux command line version of the google tool. Uploaded files with this command:

./appcfg.py update /home/[username]/[path to app.yaml]/

You have a mix of domains in your page - www.diamondlabels.com and fjedp32.appspot.com

The fjedp32.appspot.com requests look fine and appear to be coming from Google servers. The www.diamondlabels.com requests are the ones with the problem and don’t appear to be served from appspot (and are returning http 1.0 responses)

any problem with http 1.0 responses?

umm, yeah - generally HTTP 1.0 disables keep-alive (technically both can co-exist but it’s very rare that they do).
