Event based Ajax communication between server and browser

I'm going to write an application, having some worker threads on the server, and some log and status elements on the html page. logs and status are expected to be updated whenever an update is ready from the server side. well, one approach is to set up a polling mechanism, like the client sends a request on specified intervals and the server sends back the last update, (if any available).

however I wonder if there is any more efficient way like an interrupt-driven approach, on which whenever an update is ready on the server a message is sent to the client through an Ajax call. and as long as no update exists no message is transferred back and forth.

first of all, is this possible to initiate a call from the server side? I mean via Ajax. or is there any library like JQuery that facilitates such a requirement?

Thanks

Consider using web sockets (Available in HTML5) - This will allow you to skip polling an update the data immediately as the server sends up his finish request.
