I'm not familiar with EventStream of JS. But if it supports server
side events... Than it does either long polling or some sort of streaming
like hidden iframe or "never-ending" javascript etc.

There are many COMET techniques.

async_complete_response does what is defined - completes the response and
closes the connection. The client is expected to reopen one - send a new
XHR and wait again - also note that you can't get partial content
using XHR API.

If you want to not complete the response use async_flush_output 
with completion handler.
