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](http://www.example.co.uk) \*.example.co.uk;  
}

the URI = [http://something.example.co.uk/](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://www.example.co.uk) HTTP\_HOST =\> [something.example.co.uk](http://something.example.co.uk)

server {  
listen 443;  
server\_name [www.example.co.uk](http://www.example.co.uk) [secure.example.co.uk](http://secure.example.co.uk);  
}

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

the URI = [https://secure.example.co.uk/](https://secure.example.co.uk/)

// SERVER\_PORT =\> 443  
// SERVER\_NAME =\> [www.example.co.uk](http://www.example.co.uk)  
// HTTP\_HOST =\> [secure.example.co.uk](http://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.

Yes, this is correct and expected behaviour.
