	authList : ['mia:{SHA}x511ncXd+4fOnYAotcGPFD0peYo=']
});

/**

 */
http.createServer(function(req, res) {
	// Apply authentication to server.

	});
}).listen(1337);

	authFile : __dirname + '/users.htpasswd'
});

/**

http.createServer(function(req, res) {
	// Apply authentication to server.
	basic.apply(req, res, function(username) {
		res.end("Welcome to private area, " + username + "!");
	});
}).listen(1337);

Example with express framework integration

/**
 * Requesting new authentication instance.
 */
var basic = auth({
	authRealm : "Private area.",
	authList : ['Shi:many222', 'Lota:123456']
});

/**
 * Handler for path with authentication.
 */
app.get('/', function(req, res) {
    basic.apply(req, res, function(username) {
        res.send("Welcome to private area - " + username + "!");
    });
});

Example with http-proxy integration

/**
 * Requesting new authentication instance.
 */
var basic = auth({
	authRealm : "Private area.",
	authList : ['mia:supergirl', 'Carlos:test456', 'Sam:oho']
});

/**
 * Create a proxy server with custom application logic.
 */
httpProxy.createServer(function(req, res, proxy) {
	basic.apply(req, res, function() {
		proxy.proxyRequest(req, res, {
			host : 'localhost',
			port : 9000
		});
	});
}).listen(8000);

/**
 * Destination server.
 */
http.createServer(function(req, res) {
	res.end('request successfully proxied!');
}).listen(9000);
