What's your config?

What proxy_cache behavior do you want to set?

You could reasonably set proxy_no_cache, because that only applies after
accessing upstream.

You can't usefully set proxy_cache, or proxy_cache_bypass, or
proxy_cache_key, because they are all consulted before the decision on
whether or not to access upstream has been made.

Cheers,
