Thanks appa.

My question is: if the setup works with two ports, how come it stops working when the ports are switched?

Anyway, my config:

proxy_cache_path /dev/shm/proxy_cache levels=1:2 keys_zone=proxyone:10m inactive=10m max_size=100m; proxy_cache_key "$scheme$host$request_uri$cookie___user";

proxy_cache proxyone; proxy_cache_min_uses 1; proxy_cache_valid any 60s; proxy_cache_valid 404 0s; proxy_cache_valid 500 502 503 504 1s;

#>>>>>>>>>>>>>>>>>>>>>>>>>>>>> SERVER BLOCK

location @backend { internal; proxy_pass http://77.12.16.8:80; include proxy.inc; }

} # End of server block

And in Apache:
