php

I have a PHP process that takes a long time to run. I don't want the AJAX process that calls it to wait for it to finish. When the PHP process finishes it will set a field in a database. There should be some kind of AJAX polling call to check on the database field periodically and set a message.

How do I set up a jQuery AJAX call to poll rather than wait? Does the PHP script have to do anything special?

I need to create a chat like facebook chat. With Comet I need more memory to keep the connection. With Ajax polling there is a latency problem if I send request every 3-4 seconds. So... If the latency ( 3-4 seconds ) doesn't matter, Is Ajax Polling better for my case ? >>> More
