Hi Igor, thank you very much for your reply.

The _problem_ is that Nginx does not behave as the documentation describes. Entering multiple server names in one server_name directive and using $http_host do not work.

When I enter more than 1 server name I get a warning message: Restarting nginx: nginx: [warn] conflicting server name "www.xxx.com" on x.x.x.x:80, ignored (there is only one mention of this server name anywhere - I have grepped all config files looking for a runaway).

In terms of logging, $http_host (and all other variables I tried to get a host name out of) is _empty_ unless there is a server_name match on 'certain' one name in the server_name list...

What could cause $http_host to loose its value even if the server_name does not populate correctly?

I am using nginx version: nginx/1.0.11. I will try to see if I can pinpoint the issue further...

Cheers,

Luci

This may help:
http://nginx.org/en/docs/http/server_names.html

> 2. Cannot log the virtual server name (Apache %v equivalent) to the access_log. Any variable in the custom log format - ie. $server_name, $host, etc does not log the Host headers, but rather the server name string set with the server_name directive (if matched). This makes it impossible to have a combined log file for different sites set in a virtual hosting environment on the same IP address.

$http_host.
