Right now you're scheduling all of your requests to happen at the same time, just a second after the script runs. You'll need to do something like the following:

    cur = 1;

function scheduleRequest() {
    if (cur > numRequests) return;

    makeRequest({
        host: 'www.host.com',
        path: '/path/' + cur
    }, cur);

    cur++;
    setTimeout(scheduleRequest, 1000)
}

Note that each subsequent request is only scheduled after the current one completes.
