Nginx::Engine::Cookies::Resolver - Asynchronous TCP DNS resolver

SYNOPSIS

use Nginx::Engine;
use Nginx::Engine::Cookies::Resolver;

ngxe_init("./ngxe-error.log", 128);

ngxk_resolve("google.com", sub {
    my ($domain, $error, $response) = @_;

    if ($error) {
        warn "$domain: error: $error\n";
        return;
    }

    print "$domain: $response->[0]\n";

ngxe_loop;

DESCRIPTION

This is a simple ready to use asynchronous resolver for Nginx::Engine.

It tries to find nameservers in resolv.conf either in /etc or home directory or uses public DNS and issues a warning.

Nginx::Engine doesn't have built-in resolver just yet.
