The "proxy_no_cache" directive prevents caching of a response got
from an upstream (i.e., do not save to a cache). In contrast, the
"proxy_cache_bypass" directive prevents returing a response from a
cache if it's there.

The warning in question is an artifact from 0.8.x time when
proxy_no_cache used to mean both "no cache" and "bypass". It
probably should be removed.
