The proxy_no_cache with appropriate variables (e.g., map'ed or
produced with embedded perl from $upstream_http_content_length)
might be usable.
E.g. the following should disable caching of responses larger than
999 bytes or with content length not known:
map $upstream_http_content_length $toolarge {
default 1;
~^\d\d\d$ 0;
}
proxy_no_cache $toolarge;
(Untested.)
See http://nginx.org/r/proxy_no_cache for details.
