Using Variable in fastcgi_pass

[Samuel Vogel]

Maybe it would be helpful if I included my config file:
server {
        listen 127.0.0.1:81;
        server_name  localhost;

        set $userid "default";

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

        root   /www/$userid;
        index  index.html index.htm;

        location ~ \.php$ {
                fastcgi_pass   unix:/var/run/php-fpm/socket/$userid;
        }
}
