var request = require('request'),
    async = require('async');

async.series([
    function(c) {
        request('someuri', function(err, response, body) {
            console.log('Request Callback Executed');
        });
        c();
    },
    function(c) {
        console.log('Last callback/function executed.');
        c();
    }
]);
