684	"False [warn] no ""fastcgi_cache_key"" for ""fastcgi_cache"" breaks start"	Albert Szelagowski		"Since version 1.7.8 Nginx fails to start, as a result of this patch now included: http://hg.nginx.org/nginx/rev/906530c9ffd2

To reproduce use only dynamic variables in fastcgi_cache_key with no other hardcoded default values.

Example which worked before:

fastcgi_cache speed;
fastcgi_cache_key ""$is_bot$device$host$request_method$key_uri$cache_uid$http_x_forwarded_proto$sent_http_x_local_proto$cookie_respimg"";

I guess the problem is that fastcgi_cache_key is not hardcoded in the configuration but uses only dynamic variables which are available as a response to request and not on config check at daemon start.
