Map FastCGI Ports Dynamically

[justin]

Volodymyr,

Thanks for the reply.

map $http_host $user_fastcgi_port {
default 9000;
justin.my.domain.com 9001;
simon.my.domain.com 9002;
}

server_name ~^(?<user>.+)\.my\.domain\.com$;

fastcgi_pass php1.local.domain.com:$user_fastcgi_port;

Getting 502 Bad Gateway. How can I debug and see what the value of
$user_fastcgi_port is being set as?
