I'm using ngnix openreg with the default configuration form 3scale with a few additions. No matter what I do I'm getting all cache MISS in the logs.
The headers from the upstream server:
HTTP/1.1 200
Content-Length: 1517
Content-Type: application/xml
Date: Thu, 6 Oct 2016 11:03:56 UTC
Expires: Thu, 6 Oct 2016 11:04:11 UTC
Cache-Control: max-age=15
Length: 1517 (1.5K) [application/xml]
The Nginx config file:
# NEED CHANGE (defines the user of the nginx workers)
# user user group;
## THIS PARAMETERS BE SAFELY OVER RIDDEN BY YOUR DEFAULT NGINX CONF
