I would like to see which objects get cached by my nginx reverse proxy (with an apache as a backend). So far I could not find a way, only the info that its not implemented yet.
The reason is that I would like to tweak my configuration for best performance without putting too much stress on the server, as the backend is a production system. I know benchmarking would be better, but its not an option right now. So I though an alternative measure would be to monitor the cache.
Is that possible, and if yes, how? (despite patching nginx with the patch mentioned in the link above)
