I'd like to echo Marc's comment here. AJAX works fine when you have
low
latency, but with high latencies (think satellite links where the
downstream latency is 250ms [geosynchronous orbit and back], and
upstream is often higher), and it becomes a lot more of a problem.
I used such a connection on a ship at one point, and despite being a
15Mbit pipe, it was unusable for anything that expected interactivity.
I have no objections to AJAX support, but there must be a way to turn it
off.
an option to turn it off could be usefull,
but the problem you mention above should be handled transparently by the
application
the ajax in the application is responsible to interact with the customer
- not the server - so the ajax has to handle delays and take proper actions.
is see no difference in waiting for ajax to transmit and recieve data -
or waiting for a whole page to be loaded after submitting the form ...
the only difference is that loading the whole page will even take longer
than ajax loading only relevant data ...
