Issue with uwsgi_cache

[Michael Barrett]

My bad - I think I've found the cause, and it doesn't appear to be a problem with nginx or uwsgi.. but the developers application, which seems to send back the following headers, which I'm guessing nginx obliges:

Pragma: no-cache
Cache-control: no-cache, must-revalidate, no-cache=\"Set-Cookie\", private

Sorry for the repeated questions - and yay for nginx being so easily strace'able!

Thanks!
