Server_name host order

luislavena · November 23, 2011, 11:31am

Hello, I would like to know if this is correct

Will NGINX allways return the first of the provided hostname name in
from the server_name as beign the “SERVER_NAME”,

eg server_name hostname1 hostname2;

I have two server blocks in this example

server {
listen 80;
server_name www.example.co.uk *.example.co.uk;
}

the URI = http://something.example.co.uk/

// PHP APPLICATION --------------
I see as expected SERVER_NAME and HTTP_HOST

SERVER_PORT => 80
SERVER_NAME => www.example.co.uk
HTTP_HOST => something.example.co.uk

server {
listen 443;
server_name www.example.co.uk secure.example.co.uk;
}

// PHP APPLICATION --------------
again the SERVER_NAME and HTTP_HOST as i would expect

the URI = https://secure.example.co.uk/

// SERVER_PORT => 443
// SERVER_NAME => www.example.co.uk
// HTTP_HOST => secure.example.co.uk

The $server_name variable is always first name as defined by the
“server_name” directive in the server{} in question.

With default fastcgi_params as shipped with nginx, SERVER_NAME as
passed to php via fastcgi will be set to $server_name, i.e. first
name defined with the “server_name” directive.

I see as expected SERVER_NAME and HTTP_HOST

Yes, this is correct and expected behaviour.
