Forum: NGINX Logging 'return 404' to error log?

Asked this in How to... forum, but it seems not much activity, so i try 
to
post in here... Anyone know this?

Hi,
I'm have a question like title subject. I have an nginx/1.2.1 
installation,
the nginx configuration like this:

location ~ ^/abc/ {
if (!-e $request_filename) {
return 404;
break;
}
proxy_pass http://127.0.0.1:8080;
include /etc/nginx/proxy.conf;
}

config running good, but all the 404 log from this "return 404;" move to
access log. I want it move to error log, so I try use log_not_found but 
have
syntax error.

Do you have an idea how to do this?

Sorry for my poor english!

Thanks,
vinhomn
