Chloe is a real-time web server that works. The User's browser loads your page, which instantiates a connection to Chloe using JavaScript. It can then send data over that connection, which will be relayed to your app via a POST from Chloe. When you have the data that you want to send back to the browser, you can send a POST to Chloe, which will relay it back to the connected browser.
