Hello,
on 12/29/2007 02:29 PM ashore said the following:
Folks, lots of stuff around re "multipart/x-mixed-replace" , which
isn't supported on MS browsers. But i understand that they DO support
an alternative server-push approach.
I've Googled without success so far, so I wonder whether anyone here
has some pointers to subject matter?
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.
