# Javascript

Below is an example of making an HTTP request to SITE_NAME from Node.js.

    var https = require('https');
    https.get('PING_URL').on('error', (err) => {
        console.log('Ping failed: ' + err)
    });

You can also send pings from a browser environment. SITE_NAME sets the `Access-Control-Allow-Origin:*` CORS header, so cross-domain AJAX requests work.

    var xhr = new XMLHttpRequest();
    xhr.open('GET', 'PING_URL', true);
    xhr.send(null);
