Re: window.setInterval()

That made me think. AJAX is asynchronous, after all. And it made me think about server architecture, too.

If the connection were to stay open, that would tie up a socket at the TCP/IP level, and tie up a connection in the HTTP server.
Modern webservers deal with this one way or another. In the Java web server Jetty the concept is called "continuations".

Apparently the Servlet-3.0 specification allow for "suspendable requests" which will be the official way to do this.

Then the "connection in the http server" will not be a 1-1 mapping.
