bug with variables in fastcgi_pass

[Samuel Vogel]

Hey Igor,

I think I have hit a bug while trying out the feature you added in 0.7.27.

My config looks like this:
server {
    listen 127.0.0.1:81;
    server_name _;
   
    access_log  /var/log/nginx/access.log;

    set $subdir "default";

    if ($host ~ "^(.+)\.user\.domain\.net$") {
        set $subdir $1;
    }

    root   /www/$subdir;
    index  index.php index.html index.htm;
   
    location ~ \.php$ {
        fastcgi_pass   unix:/var/run/php-fpm/socket-$subdir;
    }
}


And I get the following error:
[error] 17238#0: *1 no resolver defined to resolve 
/var/run/php-fpm/socket-345232, client: 127.0.0.1, server: _, request: 
"GET /info.php HTTP/1.1", host: "345232.user.domain.net"

If I remove the variable from fastcgi_pass everything works fine!
It seems like nginx is ignoring that I try to point it to a unix socket, 
when I use a variable!

Regards,
Samy
