You can use COMET. It is an alternative way of performing AJAX requests
without keep polling for server responses.

http://www.phpclasses.org/blog/post/58-Responsive-AJAX-applications-with-COMET.html

You may want to try this forms class that comes with an AJAX plug-in
that uses a COMET implementation based on hidden iframes instead of
XMLHttpRequest.

http://www.phpclasses.org/formsgeneration

iframes are consistently supported in all browsers, so portability is
much better than using XMLHttpRequest or multipart/x-mixed-replace requests.

Here is a live example of submitting a form and receiving multiple
asynchronous updates from the server depending on the progress of a
server side operation.

http://www.meta-language.net/forms-examples.html?example=test_ajax_form

In this example case it was used to process a submitted form, but it can
be triggered by any browser event that is not really related with forms.
