Javascript

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

var https = require('https');
https.get("PING_URL");

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);
