fastcgi_cache_bypass and 502 Bad Gateway

[kaspars]

No. I am already using this check successfully for the fastcgi_no_cache
rule.

The real problem is with the *fastcgi_cache_bypass*. My understanding is
that if "fastcgi_cache_bypass 1", then Nginx will request a fresh
response from the backend and cache that response for further use where
"fastcgi_cache_bypass 0".

Is that how fastcgi_cache_bypass should work?
