AJAX and infinite loop script

[nababx]

Hi,

Do you know if I can launch a PHP script kept-alive by an infinite loop (it's a socket client script) through AJAX without blocking the other JS commands coming afterwards?

The idea is that a script is always launched, and sends returns data only when needed, and we execute this returned string little by little as it is returned on the ReadyState=3.
I am doing this to implement a chat and an alert system using socket connections, in an existing PHP application which works only through AJAX. So there are JS messages all the time.

I have made quite a lot of tries, but so far, even if the chat server sees the connections, on the client side, the script execution blocks anything which comes after - so the app is blocked.

I have seen a few posts discussing the problem, but none came with a solution. Some suggested to use a Flash interface, which I'd like to avoid, others say that IE doesn't respond to ReadyState=3.
Does any of you know more?

If you wanna have a look at the code, it is there:

Look at setTimeout and setInterval to call functions after time periods you specify.
