whats wrong with logging in content_by_lua?

[owenliang]

Somebody said that buffered log wont be flush in content_by_lua before it is full, but can be flushed in log_by_lua, What is the difference between them?

[agentzh]

@owenliang No such difference exists at all.

@owenliang nginx's access log buffering is completely controlled by the buffer parameter of nginx's access_log directive:
