I use this:

server {  
server\_name \_;  
server\_name\_in\_redirect off;  
fastcgi\_param SERVER\_NAME $server\_name;  
}

but when I inspect $_SERVER[“SERVER\_NAME”] I get this "_", but I would  
like to get the domain name, so I change to this:

fastcgi\_param SERVER\_NAME $host;

But, is this the right thing to do?

Hi

try use $\_SERVER[“HTTP\_HOST”] for host, and use “server\_name \_” for  
$\_SERVER[“SERVER\_NAME”].

I think it’s more right way for your case
