Yeah, askbot is using our haproxy/varnish setup as well as memcached, so
if upstream can tweak things to be more caching friendly that would help
for sure.

Actually in this case you might want to look at the django level one?
modules/askbot/templates/settings.erb:

MIDDLEWARE_CLASSES = (

enable... not sure anyone has fully investigated all those.
