Output option based on status cord
We use HTTP proxy AD SSO. When AD SSO is used, httplog is filled with lots of status cord 407. We're pestered with increase of I/O caused by output of status cord 407.
Because it's AD SSO, it's no doubt to request authentication. It's meaningless to output this in log intentionally. We don't want to output status code 407. So we propose addition of log output option by a status cord.
