Test URL against NO_PROXY environment variable.
console.log(process.env.NO_PROXY); // ".foo.com,*.bar.com,10.*,192.168.1."
// requires protocol
var noProxy = require('no-proxy');
noProxy('http://foo.com/'); // true
noProxy('http://www.baz.com/'); // false
// check hostname part only
var noProxyHost = require('no-proxy/hostname');
noProxyHost('foo.com'); // true
noProxyHost('baz.com'); // false
noProxyHost('192.168.1.1'); // trueNOTE: You may want to use memoization around this module.
