818	error_log host information is confusing	tamere22@…		"Hi,

I think it's a bug because log_format is not possible with error_log, and I get some strange behavior in error_logs.

Say I have 2 virtualhosts named siteA.com and siteB.com that point to my nginx (reverse proxy) both.

I put an access/deny on siteB.com based on IP.
When a remote client connects to siteB with an unauthorized IP, I read in the logs ""host: siteA.com"" or ""host: siteB.com"" randomly.

I think there should be the IP address insted of IP resolution name.

For sample :

2015/10/21 14:23:02 [error] 17272#0: *10420868 access forbidden by rule, client: 81.18.187.142, server: siteB.com, request: ""GET /index.php HTTP/1.1"", host: ""siteA.com""
2015/10/21 14:24:55 [error] 17273#0: *10431600 access forbidden by rule, client: 81.18.187.142, server: siteB.com, request: ""GET /index.php HTTP/1.1"", host: ""siteB.com""

the ""host: "" part is one of my dns alias that target my nginx reverse proxy, and is random each time on the logs. Whereas the ""server :"" part is good and revelant.
